The cause of dispersion of light through the prism is that white light has a range array of seven colours, and each of those has a subsequent angle of deviation. As such, when light passes through a prism, different colours deviate from different angles. Therefore, those colours get separated...
Refraction is commonly explained in terms of the wave theory of light and is based on the fact that light travels with greater velocity in some media than it does in others. When, for example, a ray of light traveling through air strikes the surface of a piece of glass at an oblique an...
Angle of refraction through a prism Homework Statement In a physics lab, light with a wavelength of 570nmtravels in air from a laser to a photocell in a time of 17.5ns . When a slab of glass with a thickness of 0.890m is placed in the light beam, with the beam incident along the...
One of the glass prism is situated above the glass slab while the other is below the glass slab.Question: 8How does the action of the convex lens differ from that of a concave lens on a parallel beam of light incident on them? Draw diagrams to illustrate your answer....
Is the index of refraction constant for a given medium? If we have a medium (say, glass) with an index of refraction, n=1.33, the speed of light in it will be c/1.33. However, blue light travels slower in glass than does red light. Since c is constant and the speed of light is...
It does not matter whether there is a change of medium or there is a change in the speed of light, but the frequency always remains the same. Also frequency,

Consider an optical system made of an unknown number N of layers of homogeneous transparent plates with different unknown refraction indices. Observing beams of monochromatic light through the system, find the number N of plates together with their respective indices and their thicknesses. The mathemat...
When light bounces off of an object it is either reflected or scattered, and when light passes through it is either transmitted or refracted. During transmission light passes straight through a medium, and during refraction the light changes direction by some degree as it passes through a medium...
