When a light ray enters into glass medium from water at an angle of incidence 0^(@) , what would be the angle of refraction?
a lens of glass is immersed in water. How is power of lens affected ?
A light wave travels from glass to water. The refractive index for glass and water are 3/2 and 4/3 respectively. The value of the critical angle will be:
The refractive index of water is 4//3 and that of glass is 3//2 . A beam of light enters glass from water. For what angle of incidence will the refracted light be completely polarised ?
As light enters from air into glass slab, its wavelength
A light ray has a wavelength of 5,000 Å in air. How will its wavelength and frequency change entering in the glass of refractive index 1.5 ?
When light enters from air to water, then its
Assertion : A ray of light entering from glass to air suffers change in frequency. Reason : Velocity of light in glass is more than that ni air.
