Formatives 7, 8, and 9: Wave Properties, Velocity, and Energy

The full length of a wave from a crest to a crest is...

• frequency

• amplitude

• node

• wavelength

• trough

What does the amplitude measure?

• The distance from the middle resting line to the top of the crest

• the distance from node to node

• the distance from the bottom of the trough to the top of the crest

• the distance from one crest to a crest later down the wave.

How can you calculate the velocity of a wave?

• multiply the wavelength times the frequency

• divide the wavelength by the frequency

• multiply the wavelength times the frequency squared

• divide the frequency by the wavelength

what is the velocity of a wave with the wavelength 10 meters per wave and frequency of 5 waves per second?

• velocity is 2 meters per second

• velocity is 15 meter per second

• velocity is 50 meters per second

• velocity is 50 waves per waves

• velocity is 2 meters per wave

How does changing the amplitude affect the energy of a wave?

• Increasing the amplitude increases the energy in the wave.

• Increases the speed of the wave.

• Changes the wavelength

• Decreasing the amplitude increases the energy in the wave

How does the frequency change the energy in a wave?

• Frequency does not affect wave energy

• Increasing frequency decreases the energy in a wave

• Increasing frequency increases the energy in a wave

• Changing frequency only changes the wave velocity

Wavelength and frequency are related in what way?

• directly; they increase and decrease together

• directly squared; when one increases the other increases by the same factor squared

• inversely squared; when one decreases the other increases by the same factor squared

• inversely; when one increases the other decreases

Which waves have more energy based on their wavelength?

• longer wavelengths because they have more distance

• shorter wavelengths because they are moving faster

• shorter wavelengths because their frequency is low

• longer wavelengths because frequency is high

which wave has the longer wavelength?

• the top wave

• the bottom wave

• neither because they are the same

• neither because the wavelengths are measured incorrectly
