Light travels from air into glass of RI 1.5. If the wavelength in air is 6000 Angstroms, what is the wavelength in glass?
A point source of light is placed at the bottom of a tank of water (n=4/3) of depth 1m. The area of the surface of water through which light can emerge is:
A ray of light is incident at 60 degrees on one face of an equilateral prism. If it suffers minimum deviation, the angle of deviation is:
What is the relation between velocity (v), frequency (f) and wavelength (λ)?
If two plane mirrors are kept at an angle of 60 degrees to each other, the number of images formed is:
