Name two things that move through space as waves. Light and sound.
Which has a higher frequencey: the voice of a man, or the voice of a woman? The voice of a woman has a higher frequency.
What overlaps what in constructive interference? the crest of one wave overlaps another.
what moves faster: sound going through water or sound moving through solids? Sound moves faster through water.
How do transverse waves move? In right angles.
What is an example of a longitudinal wave? sound waves.
When a sound soure moves towards you, do you measure and increase or decrease in the wave speed? NEITHER. the wave speed stays the same, however, the frequency changes.
What shape is a bow wave? a V-shape.
What shape is a shock wave? A cone.
Can a subsonic aircraft make a sonic boom? No, it's a SUBsonic aircraft, and sub sonic means that it can't go faster than the speed of sound.

What is a sonic boom cloud made of? It is made of compressed air.
If a wave moves faster than the medium, does the V shape get narrower of wider? It gets narrower.
Where do standing waves occur? In musical instruments and organ pipes.
Does it take ore energy o produce a wave with a higher amplitude or a lower amplitude? It takes more energy to produce a wave with a higher amplitude.
