Light of wavelength 500nm traveling in air is incident along the
normal on Face A of a 60-60-60 glass prism of refractive index
1.52, as shown in the figure.
a) The refracted ray is incident to Face B. Calculate the angle
of incidence of the ray, the angle of refraction of the refracted
ray (if any) and the angle of reflection of the reflected ray. Draw
the rays.

water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
of a material, denoted by n, gives an indication of the speed of...

The index of refraction for red light in water is 1.331 and that for blue light is 1.340. If a ray of white light enters the water at an angle of incidence of 61.55o, what are the underwater angles of refraction for the blue and red components of the light? (Enter your answers to at least two decimal places.) (a) blue component (b) red component Need Help? Read It The light beam shown in the figure below makes an angle...
