	The refractive index of a certain glass is 1.5 for light whose wavelength in vacuum is 6000 Å. The wavelength of this light when it passes through glass is
	When light travels from one medium to the other of which the refractive index is different, then which of the following will change
	A light wave has a frequency of $4 imes {{10}^{14}}$Hz and a wavelength of $5\times {{10}^{-7}}$ meters in a medium. The refractive index of the medium is
	How much water should be filled in a container 21 cm in height, so that it appears half filled when viewed from the top of the container (given that $_{a}{{\mu }_{\omega }}=4/3$)
	Light of different colours propagates through air
	Monochromatic light is refracted from air into the glass of refractive index $\mu $. The ratio of the wavelength of incident and refracted waves is
	A monochromatic beam of light passes from a denser medium into a rarer medium. As a result
