What is the shape of the wavefront on earth for sunlight?
Answers (1)
Explanation:-
The sun is at an exceptionally large distance from Earth. Assuming it as a point source of light at infinity, as seen from Earth, we can conclude that the radius of the wavefront from the sun to the Earth is infinite. This would mean that the rays are perpendicular to Earth and the wave front is almost a plane.
Sunlight is composed of light rays coming from a distant source, i.e., the Sun. The Sun is very far from the Earth (about 150 million kilometers away), so the rays that travel from the Sun to Earth are nearly parallel when they reach Earth.
