Question

Between the moon and Earth, there is an empty vacuum. Which statement describes whether sound and light waves are able to travel from Earth to the moon?(1 point)

Answer 1

Light waves can travel from Earth to the moon, while sound waves cannot. This is because light is an electromagnetic wave and does not require a medium to propagate, allowing it to travel through the vacuum of space. In contrast, sound waves are mechanical waves that need a material medium (such as air, water, or solid materials) to travel, so they cannot propagate through the vacuum between the Earth and the moon.
