Question

The main difference in the phenomenon of interference and diffraction in light waves is that,

• A. diffraction is due to interaction of waves derived from the same source, whereas interference is the bending of light from same wavefront.
• B. diffraction is caused by reflected waves from a source where as interference is caused due to refraction of waves from a surface
• C. diffraction is due to interaction of light from the same wavefront whereas interference is the interaction of two waves derived from the same source.
• D. diffraction is due to interaction of light from the same wavefront whereas interference is the interaction of waves from two isolated sources.

Answer 1

The correct option is C diffraction is due to interaction of light from the same wavefront whereas interference is the interaction of two waves derived from the same source.

Diffraction is due to interaction of light from the same wavefront whereas interference is the interaction of two waves derived from the same source

Hence, $\left(B\right)$ is the correct answer.
