Sound requires a medium to travel. Sound cannot travel in vacuum in space while light can. Therefore, the receiver from earth receives only light sent from moon, not sound.

Explanation:

Sound is created by vibrations that requires medium to travel. The medium can be solid, liquid, or gas. Whatever it is, a medium is required.
In space, there is no solid, liquid, or gas. In other words, it is vacuum. Sound waves cannot travel through vacuum.
Light waves, on the other hand, can travel through vacuum. Hence, if the transmitter on moon emits sound waves and light waves, receiver from earth picks only the light waves.
