Q136 / 160 · AP EAMCET 2020 (21 Sep Shift 2) · Physics

Which of the following generates a plane wavefront?

A
Point source
Correct answer
B
Extended source
C
Monochromatic source
D
All light sources

Solution

An extended source produce plane wavefront. A point source produce spherical wavefront.

Hence, the correct answer is option: 'B'.
