The correct answer for this question is letter (B) The electromagnetic waves reach Earth, while the mechanical waves do not. The sun generates both mechanical and electromagnetic waves. Space, between the sun and the earth is a nearly vacuum. So mechanical wave can not spread out in the vacuum.
The answer is B. The electromagnetic waves reach Earth, while the mechanical waves do not. Electromagnetic waves have the capacity to travel in a vacuum through the vibration of the atoms around the Sun. Mechanical waves however, need a medium in order to travel in a vacuum.
