100

This is the distance a wave travels before it repeats itself.  

What is wavelength?

100

High frequency waves have _____ wavelengths

What is short?

100

Because of the Doppler Effect, this appears to happen to the pitch of the sound generated from a siren as the siren moves towards you.

What is increases (or equivalent)?

100

This type of wave moves matter forward and backward in the medium in the same direction as the wave...

What is a longitudinal wave?

100

These points on a standing wave do not move.

What are nodes?

100

This is what we call two waves overlapping in the same medium.

What is interference?

100

These are the two main types of waves.  (Two answers)

What are longitudinal and transverse?

100

Humans can hear up to this range of frequency.

What is 20,000 Hz?

100

In a flute, this part of the wave is positioned at the open end of the tube.

What is an antinode?

100

As amplitude of a sound wave increases, this quantity increases.

What is loudness (or equivalent)?

100

This is the unit of loudness in sound.

What is decibels?

100

This is the type of interference when the crest of one wave overlaps the crest of another.

What is constructive interference?

100

When two sounds of similar frequencies are played, the combined wave's loudness changes over time.  What do we call this changing amplitude?

What is a beat?

100

This is the harmonic for a standing wave with two antinodes (two loops of your slinky).  

(Answers should be 'first', 'second', 'third' etc.)

What is the second harmonic?

100

This is the matter that a wave passes through.

What is the medium?

100

This is an area of constructively interfering waves that are created by something going very, very fast.

What is a sonic boom?

100

These sit inside your cochlea and wiggle around when you hear sound.  Their lengths align to different wavelengths, and if they break, they can't grow back.

What are hairs?

100

Increasing the tension of a string will do this to the waves traveling down the string.

What is increase its speed 

or increase its frequency 

or decrease its wavelength?

100

This is energy that is created by a disturbance.  Typically it travels (propagates) through a medium.

What is a wave?

100

The wave created from a single disturbance, such as clapping your hands once, is not a standing wave.  Instead, it is known as a...

What is a pulse?
