Question

Sketch the wavefront that will emerge from a distance source of light like a star.​

Answer 1

The portion of the wavefront of light from a distance star intercepited by the earth: Since a small area on the bourface of s a large sphere is nearly planar, so the portion of the wavefront of light from a distance star intercepted by the earth is a plane wavefront.

Answer 2

Answer:

The wavefront that will emerge from a distance source of light like a star in straight line a plane wave front.

Explanation:

The part of a distant star's wavefront that is intercepted by the earth:

• The fraction of the wavefront of light from a distant star intercepted by the earth is a plane wavefront because a small area on the bourface of a huge sphere is almost planar.
• When a point source is at focus, the rays coming out of the convex lens are parallel, resulting in a plane wavefront.
