Is Light a Wave or a Particle?

Water and sound waves have the ability to travel around corners, around obstacles and through openings.The most common example is the reflection of light waves off mirrored surface results in the formation of an image.involves a change in direction of waves as they pass through an opening or around an obstacle in their path.Huygens believed that ether vibrated in the same direction as light, and formed a wave itself as it carried the light waves.Thinking this way, he concluded that light waves traveled through each of the slits, creating two separate wave fronts.

Introduction To Beats Frequency Philosophy Essay

The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium.A sound wave can be represented as a sine waves, and you can add sine waves of different frequencies to get a graphical representation of the waveform.Whenever two wave motions pass through a single region of a medium simultaneously, the motion of the particles in the medium will be the result of the combined disturbance due to the two waves.Now if two sound waves interfere at a given location in such a way that the compression of one wave meets up with the rarefaction of a second wave, destructive interference results.The interference of sound waves causes the particles of the mediu...

Sound Waves and Room Acoustics Essay

Reflections: they are echo-like sounds that reflect off walls and reach your ears slightly after the original sound, the ear however –and the whole auditory system, which includes the brain- detects this as part of the original sound.This happens when the air particles are driven into motion by the sound waves, then attempt to pass through the dense sound-absorbing material, resulting in a very small amount of heat-generating friction.Standing waves and room resonance modes Any time you have a pair of parallel reflective surfaces (like room walls, or the floor and ceiling), you’re going to experience some degree of a phenomenon known as “standing waves.” Standing waves distort the bass and lower midrange frequencies from 300 Hz on down.S...

Effects Of Noise In A Data Communication

Each of these systems use different types of unguided media for example satellite uses microwaves, but this report will focus on wireless and the noise that can affect the radio waves wireless uses.When using Unguided Media in a communications system, the signal is sent through the air via an antenna in the form of electromagnetic waves, these waves have no specific path to follow... Multi Path interference is where a receiver receives multiple copies of the same signal, at delayed times, this mainly affects radio, as satellite or microwaves generally are line of sight so there would be no obstacles present for reflection to take place.Overall I would say I learned a great deal more about the complexity of noise and data communication s...

Observing Wave Pulses

PART 2 – Longitudinal waves .PART 3 – Waves at a boundary .The phenomenon is the result of interference (and reflection) which is when waves are superimposed, and their energies are either added together or cancelled out.Once this state is achieved, the wave will ‘dissolve’ and the component waves will re-appear but travelling, this time in the opposite direction to which they came.On the other hand, if the spring is consistently producing lower frequency waves, there will be less waves with smaller amplitudes.

Ripple Effect

I think this happens because the waves still continue on their path but create the illusion that they are going in mulitple directions.When the frequency is increased it just creates more waves and same goes for when its decreased, less waves.What happens to waves when they encounter obstacles of different shapes?When it is extremely slow the waves are created all around the source and not just behind it, but when it is fast that’s when the waves are just created behind the source.What happens with the wave patterns?

Optical Fibres

When a light wave passes from one density of medium to another, its speed may change.It has been used since the early 1960’s.When the speed of the light wave changes speed, it causes the wave to also change direction.The idea of using light to relay messages is not a new one.If a medium is dense it causes the light wave to bend toward the normal.

Applications of Ultrasound in Medicine

This raises the moral awareness of fetuses and if they should be exposed to the waves emitted, which can bring injurious damage.Although it has contrasting advantages and disadvantages, and is not worth recommending it should not discourage anyone from using ultrasound waves.During the process of scanning the waves also erode pieces of gallstone which reside within our organs, with their constant vibrations.A transducer is then used to generate the ultrasound waves and detect any echoes it receives from the reflected waves.[5] Gel is applied to the patients body to reduce friction with the transducer and aid the transmission of ultrasound waves.

Development of Surface Plasmon Resonance (SPR) Sensor

A collimated p-polarized light beam, entering from the glass side undergoes a total internal reflection and interacts with the metallic layer at the critical angel of incidence (as shown in Figure 2).As the meaning of “Evanescent” is “tending to vanish”, the amplitude of evanescent waves decays exponentially with the distance from the point of incidence, to the interface of the media 1 and 2.The Evanescent waves, a near-field wave, are produced in the lower refractive index medium 2 (air or dielectric) under the TIR condition.A typical SPR sensor consists of a dispersive element, such as prism or a plane reflection grating, coated with a metallic layer (Gold) and a dielectric layer (usually polymers or bio molecule layers).SURFACE PLASMO...

Radar Essay

The extent to which an object reflects or scatters radio waves is called its radar cross section.If electromagnetic waves traveling through one material meet another, having a very different dielectric constant or diamagnetic constant from the first, the waves will reflect or scatter from the boundary between the materials.This means that a solid object in air or in a vacuum, or a significant change in atomic density between the object and what is surrounding it, will usually scatter radar (radio) waves from its surface.Short radio waves reflect from curves and corners in a way similar to glint from a rounded piece of glass.Radar waves scatter in a variety of ways depending on the size (wavelength) of the radio wave and the shape of the ...

The Electromagnetic Waves And Spectrum

The longest waves are radio waves, which have wavelengths of many kilometres.Photon energy is directly proportional to the wave frequency, so gamma rays have the highest energy (around a billion electron volts) and radio waves have very low energy (around femto electron volts).We would now focus on how these electromagnetic waves which carry energy and momentum are used in various applications round the globe.Though the work of Maxwell and Hertz was foundational to the harnessing of radio waves for human use, the practical use of radio had its beginnings with Marconi.In most schematic representations of the spectrum, radio waves are shown either at the left end or the bottom, as an indication of the fact that these are the electromagneti...

Properties of Light Essay

A number of physicists have considered the polarization as one of the important properties of different waves, especially the light waves.The term of intensity has mostly been taken for defining the property of waves; however, the water can also be considered for the defining of intensity, but most of the scientists have considered the utilization of intensity for the waves specifically.Moreover, when a wave passes through different mediums, the refraction can be observed in these waves.In addition, most of the light waves have long, as well as, wide wavelengths that are mostly infinite in measurements, which results in their consideration as plane waves.played a vital role in the development of concepts related to the light waves by the...
