his is what happens to the wavelengths of the waves made by dipping your finger in a pond faster and faster.
What is they get smaller and smaller
100
An echo is an example of this behavior of sound waves.
What is reflection?
100
What has a foot but no legs?
What is snail
200
The distance between two successive identical parts of a wave.
What is What is the wavelength?
200
The resulting change in period of a wave if you double the frequency.
What is cut in half?
200
this wave goes in a parallel line
What is a transverse wave
200
This behavior explains why low frequency sounds can be heard better around corners than high frequency sounds.

300
This is the name we use to describe the resulting pattern when 2 or more sets of periodic waves meet at the same place at the same time.
What is n interfernce pattern?
300
This is the wave pattern established in the air inside a bottle when air is blown across the open neck of the bottle.
What is a standing wave?
300
You throw away the outside and cook the inside. Then you eat the outside and throw away the inside. What did you eat?
What is a chicken
400
It describes when 2 waves meet to produce a larger amplitude wave.

400
This is the name of the phenomenon of straight waves bending as they pass through narrow openings.
What is What is diffraction?
400
This is when two sound waves meet at the same place at the same time and become louder.
