Wave Optics Tes...

As a result of interference of two coherent sources of light, energy is :

Waves that cannot be polarized are :

Statement-1: Newton’s rings are formed in the reflected system when the space between the lens and the glass plate is filled with a liquid of refractive index greater than that of glass, the central spot of the pattern is bright.

Statement-2: This is because the reflection in these cases will be from a denser to rarer medium and the two interfering rays are reflected under similar conditions.

Statement-1: Radio waves can be polarized.

Statement-2: Sound waves in air are longitudinal in nature.

Statement-1: In Young's double slit experiment, the fringe width for dark fringes is equal to that for bright fringes.

Statement-2: In Young's double slit experiment, if the experiment is performed with a source of white light, then only dark and bright fringes are observed.
