Wave Types and Classifying
What is a type of wave that moves parallel to the direction of the wave motion?
Longitudinal wave
A disturbance that transfers energy
Wave
How often a wave occurs in one second is the wave's
Frequency
What medium does sound travel through slowest?
Gas
As temperature decreases, the speed of sound
Decrease
Waves that require a medium are called _______ waves.
Mechanical Waves
A transverse wave has an amplitude of 2.4 m. What is the distance between the top of a crest and bottom of a trough?
4.8
What happens to the wavelength if you increase the frequency?
If you increase frequency, the wavelength gets shorter.
When one part of a vibration pushes air particles together, they form a
Compression
A buzzer is ringing inside the bell jar. All of the air is pumped out. What will happen to the sound?
There will be no sound (Sound needs air molecules to travel)
How are waves classified?
By how they move.
What do the blue lines represent on this wave model?
Wavelength
How is energy of a wave and amplitude of a wave related?
More energy, the greater the amplitude.
Sound travels FASTEST through which of these materials?
Metal
What do all three examples have in common?
The examples are producing a sound wave
What happens when you squeeze a spring or slinky?
Compression
The waves shown travel at the same speed. Which has the higher frequency?
Wave 3
Tom is making waves in a tub of water by pushing a block up and down. What can he say about the properties of the waves?
Pushing harder on the block gives the waves more energy, and they will have a larger amplitude
How do sound waves move when they enter the room?
The sound waves spread out.
Which answer best explains what causes a wave?
Vibrations
