Waves Test #1 Review

A string is attached to two fixed points & is compressed on one end and released. The resulting wave travels back & forth b/w until it comes to a stop.  This is an example of...

• transverse wave
• longitudinal
• superpositional
• refracted

A sound wave can be transmitted through all of the following except...

• a gas
• a liquid
• a solid
• a vacuum

The distance between Earth and the Moon was determined by measuring the time it took for light from Earth to travel to the Moon and back.  Why wasn't sound waves used?

• Sound must move through a medium.
• Sound would change frequency.
• Sound would move too slowly to be accurate.
• Sound moves more slowly in Earth's atmosphere than in space.

The stretched part of this wave is called...

• compression
