Waves Concepts
Can sound travel through outer space? Explain why or why not.
No - space is a vacuum so there is no air (medium). Sound is a mechanical wave so it needs a medium to travel.
What is the velocity of a wave that travels 1000m in 20 seconds?
50 m/s
What is Mercury?
What year did the terrorist attacks in the US on the World Trade Centers and Pentagon take place on September 11?
2001
This is the longest river in the world
What is the Nile?
Longitudinal
What is the velocity of a sound wave that has a wavelength of 9m and a frequency of 38 Hz?
342 m/s
Evaporation is the word to describe a liquid changing into a gas. What word describes a gas changing into a liquid?
What is Condensation? (Oh no Cleo, the condensation!)

Would a sound wave travel fastest through air, water, or a solid metal block? Explain why
Metal block. Sound waves move faster in denser mediums.
