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. |
True or false: a sonic boom only happens when a supersonic plane breaks the sound barrier. | FALSE. a sonic boom can happen whenever something goes 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. |
