Explain optical path in denser medium

When a ray of light travles from an optically more denser medium to an optically less denser medium, the angle of incidence is always _____ than the angle of refraction.

When a ray of light travels from an optically less denser medium to an optically more denser medium, the angle of incidence is always less than angle of refraction.

When a light wave in a rarer medium is reflected from the surface of an optically denser medium, it suffers a phase change of (in radian)

A : If a wave moving in a rarer medium , gets reflected at the boundary of a denser medium , then it encounter a sudden change in phaso or pi . R : If a wave propagating in a denser medium , gets reflected from rarer medium , then there will be no abrupt phase change .

Fill in the blanks: Q: Critical angle is the angle of ____in denser medium for which the angle of ____in rarer medium is ____-

Using Huygen.s principle, verify Snell.s law of refraction of plane wave propagating from denser medium to rarer medium.

Which of the following phenomena support the wave theory of light? 1. Scattering 2.Interference 3. Diffraction 4. Velocity of light in a denser medium is less than the velocity of light in the rare medium

Wave length of light in denser mediumis 4000Å , it is grazing into a rarer medium. If critical angle for the pairof mediam is sin^(-1)(2/3) then the wave length of light in rarer medium is

Which of the following statement is // are correct about the refraction of light from a plane surface when light rays is incident in denser medium. [ C is critical angle ]
