between the moon and earth, there is an empty vacuum. Which statement describes whether sound and light waves travel to the moon

Question

1. sound can travel from earth to the moon, but not light
2. Light can travel from earth to the moon, but not sound
3. both sound and light can travel from earth to the moon
4. neither sound nor light can travel from earth to the moon

Answer 1

The correct statement is:

2. Light can travel from Earth to the moon, but not sound.

This is because light is an electromagnetic wave and does not require a medium to travel; it can propagate through the vacuum of space. On the other hand, sound is a mechanical wave that requires a medium (such as air, water, or solid matter) to travel, so it cannot move through the vacuum of space between the Earth and the Moon.
