Wave Optics Tes...

Huygen's wave theory allows us to know

Assertion: No interference pattern is detected when two coherent sources are infinitely close to each other.
Reason : The fringe width is inversely proportional to the distance between the two slits.

Light travels faster in air than that in glass. This is accordance with

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: The resolving power of a telescope is more if the diameter of the objective lens is more.
Reason: Objective lens of large diameter collects more light.

Which one of the following does not support the wave nature of light?

Which of the following generates a plane wavefront?

High quality lens system for optical instrument is made by using ..............

Doppler's effect is sound in addition of relative velocity between source and observer, also depends while source and observer or both are moving. Doppler's effect in light depend only on the relative velocity of source and observer. The reason of this is.

What will happen to the light at the third maxima on both sides of the zeroth fringe in a Young's double slit experiment ?
