When a sound wave travels from the air into a lake, what happens to its speed, and why?

An astronaut drops a hammer on the surface of the Moon. Why would an observer nearby be unable to hear the sound, even though they could see the hammer fall?

Light waves are observed traveling through several different substances: outer space, air, water, and diamond. In which of these materials will the light waves move at the slowest speed?

Which of the following describes the behavior of waves moving from a gas into a liquid?
