This is the distance a wave travels before it repeats itself.
What is wavelength?
High frequency waves have _____ wavelengths
What is short?
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)?
This type of wave moves matter forward and backward in the medium in the same direction as the wave...
What is a longitudinal wave?
These points on a standing wave do not move.
What are nodes?
This is what we call two waves overlapping in the same medium.
What is interference?
These are the two main types of waves. (Two answers)
What are longitudinal and transverse?
Humans can hear up to this range of frequency.
What is 20,000 Hz?
In a flute, this part of the wave is positioned at the open end of the tube.
What is an antinode?
As amplitude of a sound wave increases, this quantity increases.
What is loudness (or equivalent)?
This is the unit of loudness in sound.
What is decibels?
This is the type of interference when the crest of one wave overlaps the crest of another.
What is constructive interference?
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?
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?
This is the matter that a wave passes through.
What is the medium?
This is an area of constructively interfering waves that are created by something going very, very fast.
What is a sonic boom?
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?
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?
This is energy that is created by a disturbance. Typically it travels (propagates) through a medium.
What is a wave?
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?
