Front (Question)

What two types of wave are there?

Back (Answer)

• Transverse • Longitudinal

Front (Question)

Give an example of a longitudinal wave

Back (Answer)

Sound

Front (Question)

Describe how longitudinal waves transfer energy.

Back (Answer)

Vibrations are parallel to energy transfer

Front (Question)

Give an example of a transverse wave

Back (Answer)

• All electromagnetic waves • A ripple on water • A wave on a string

Front (Question)

Describe how transverse waves transfer energy.

Back (Answer)

Vibrations are perpendicular to energy transfer

Front (Question)

Compare the sound of the two waves in the image in terms of loudness and pitch.

Back (Answer)

• They have the same loudness. • Wave B has a higher pitch.

Front (Question)

Name the properties of the wave labelled a) and b)

Back (Answer)

a) Wavelength b) Amplitude

Front (Question)

Name the two regions of a longitudinal wave labelled ‘C’ and ‘R’.

Back (Answer)

C = compression R = rarefaction

Front (Question)

What equation links wave speed, frequency and wavelength?

Back (Answer)

Wave speed = frequency x wavelength V = 𝘧 λ

#12

Front (Question)

What are gamma rays used for?

Back (Answer)

• Killing cancer cells • Sterilizing medical equipment

#13

Front (Question)

What does frequency mean?

Back (Answer)

The number of complete waves passing a certain point in a second (1 Hz is 1 wave per second)

Back (Answer)

Ultraviolet waves, X-rays and gamma rays

#15

Front (Question)

Which EM wave causes skin cancer?

Back (Answer)

Ultraviolet waves cause skin cancer

#16

Front (Question)

Write the electromagnetic spectrum in order from longest to shortest wavelength.

Back (Answer)

#17

Front (Question)

Compare the sound of the two waves in the image in terms of loudness and pitch.

Back (Answer)
