How do the wavelengths of the transmitted waves compare to the wavelengths of the incident wave?
miracles.
How do the widths of the reflected and transmitted waves compare to the width of the incident wave?
The width of the reflected wave is the same as that of the incident wave. The width of the transmitted wave depends on the electro-optical or sonic density of the second medium.
How is an incident ray related to a reflected ray?
The relation between the incident ray and reflected ray is described by the material which is reflecting the incident ray. depending upon the material used the incident ray is scattered or reflected or refracted or transmitted or absorbed. For example if you take rainbow the sun light is incident on the rain drop , it reflected back of drop several times and due to that we get the rainbow with various colours.
What is the difference between reflectivity and reflectence?
reflectivity is the fraction of incident radiation reflected by a surface. In general it must be treated as a directional property that is a function of the reflected direction, the incident direction, and the incident wavelength. However it is also commonly averaged over the reflected hemisphere to give the hemispherical spectral reflectivity:reflectance a measure of the ability of a surface to reflect light or other electromagnetic radiation, equal to the ratio of the reflected flux to the incident flux.
What is difference between incident ray and a reflected ray?
A ray of light which strikes the surface is called incident ray and a surface which is reflected is called a reflected ray

What happens when light hits a blue surface?
Depending on the range of wavelengths that comprise the incident light, some of it may be absorbed and some may be reflected. If blue wavelengths are present in the incident light, then the blue is mostly reflected, and any other wavelengths are mostly absorbed. This is the main reason that the surface acquires the reputation of being 'blue'.

What is the fraction of total radiation that is reflected by any surface called?
It is the reflectivity of the surface. However, it is important to note that the reflected fraction depends on the wavelength of the incident light.

What is standing waves electromagnetic theory?
When a traveling wave is reflected, the reflected wave and incident wave can add to porduce peaks and nodes at different distances along the path. These are measures of the EM wavelength.
What causes the colorful swirls in soap bubbles?
When an incoming ray of light strikes the outer surface of a bubble, part of the light ray is reflected immediately, while the other part is transmitted into the soap film. After reaching the inner surface of the film, this transmitted light ray is reflected back toward the outer surface. When it leaves the bubble, it travels in the same direction as the ray that was immediately reflected and is, therefore, parallel to that ray. If these two rays of light are reflected back so that their wavelengths are "out of phase" with each other, the second ray will partly cancel out the reflection of the first ray. This is called destructive interference, which results in a reduction of color intensity. If, however, the wavelengths of the two reflected rays are "in phase," they will enhance each other. This is called constructive interference. The light rays that are reflected off the inner surface of the bubble travel further than the light rays that are reflected off the outer surface. Some wavelengths will interfere destructively and others constructively, depending on the extra distance traveled by a transmitted-and-reflected ray. Whether the reflected rays are in or out of phase with each other depends on the extra distance (through the film and back) that the second ray must travel before rejoining the first ray. This distance depends on the angle of the incident light and the thickness of the film.White light is made up of different colors, corresponding to specific wavelengths. As the film thickness changes, the extra distance the ray must travel changes. Interference is constructive when the total extra distance matches a specific wavelength of light, and is destructive when it is half a wavelength. So if white light shines on a bubble, the film reflects light of a specific hue, and this hue changes with the film's thickness.The iridescence of a soap bubble, which seems to contain a wealth of changing color, stems from light striking the bubble from varied angles. The path length varies with the angle of incident light, giving varying path differences for the internally and externally reflected rays at different points on the bubble. This means that, even if the soap film is of uniform thickness, different colors can be seen. Light entering the bubble directly travels a shorter path than light entering at a wider angle. This allows different wavelengths to undergo constructive and destructive interference, so different colors are perceived.
What is difference between incident ray and a reflected ray?
A ray of light which strikes the surface is called incident ray and a surface which is reflected is called a reflected ray
Why an exssecively thin film appears black in the reflection of light?
Destructive interference. If the sheet is very thin, near half the wavelength of the incident light then light reflected from the top layer is out of phase with light reflected from the bottom layer. These two reflected light waves will cancel each other out.
What is angle of incident if the reflected ray is 90 degree to incident ray?
The angle of incident is 45 degrees. The incident and reflected ray have the same magnitude and if the sum of the magnitudes is 90 degrees the incident is 45 degrees.
What are incident and reflected rays?
incident ray: the ray that strikes the object reflected ray: the ray that is directed away from the object
