Assertion : Light shows the phenomena of interference, diffrection and polarisation.
Reason : Because light behaves as corpuscles.

Draw a neat labelled diagram showing the plane of vibration and plane of polarisation for polarised light.

Assertion : All bright interference bands have same intensity. Reason : Because all bands do not receive same light from two sources.

Assertion : All bright interference bands have same intensity. Reason : Because all bands do not receive same light from two sources.

Assertion : A white source of light during interference forms only white and black fringes. Reason : Width of fringe is inversely proportional to the wavelength of the light used.

Assertion (A) : Transverse wave nature of light is proved by polarisation Reason (R ) : According to Maxwell, light is an electromagnetic wave but not mechanical wave

Assertion : Sound waves travelling in air cannot be polarised. Reason : Polarisation is property of light waves only.
