Bragg's Law| Destructive Interference

Braggs Law

There is a destructive interference between the two waves of wavelength lambda coming from two different paths at a point. To get maximum sound or constructive interference at that point, the path of one wave is to be increased by

Assertion (A) : When tiny circular obstacle is placed in the path of light from some distance, a bright spot is seen at the centra of the shadow of the obstacle. Reason (R ) : Destructive interference occurs at the centre of the shadow.

Statement-1 : Energy is created during constructive interference and it is destroyed during destructive intference. Statement-2 : Because in constructive interference, the fringes are bright and in destructive interference, the fringes are dark.

Two waves of intensities I and 4I produce interference. Then the intensity at constructive and destructive interference respectively is –

What are coherent sources ? Define interfernece of light. Obtain the condition for constructive and destructive interference of light .

The path length difference between two waves coming from coherent sources for destructive interference should be

Write the relationship between the path difference and the wavelength of light used for constructive and destructive interference of light.
