IGCSE 3b. Properties of Waves

What two things can a wave transfer?

• Energy
• Matter
• Light
• Information

Waves do not transfer ....

• Energy
• Matter
• Light
• Information

Fill in the blanks: All waves can be __________ and __________.

• Heard
• reflected
• refracted
• Seen

Transverse waves oscillate __________ to the direction that energy is transferred.

• perpendicular
• parallel

Longitudinal wave oscillate __________ to the direction that energy is transferred.

• parallel
• perpendicular

Which letter in the picture shown correctly measures amplitude?

• A
• B
• C
• D

Define period of a wave.

• The time taken for one wave
• Number of waves that pass a point per second
• The time taken for one wave to pass a point
• The distance travelled by a wave in one second

Define frequency of a wave.

• Number of waves
• Number of waves that pass a point per second
• The time taken for one wave to pass a point
• The opposite of wavelength

What is the relationship between frequency and time period?

• frequency = 1/ time period
• frequency = time period / 1
• Measured in Hertz
• Directly proportional

What is the relationship between (wave)speed, frequency, and wavelength?

• wavelength = (wave)speed × frequency
• frequency = (wave)speed × wavelength
• (wave)speed = frequency / wavelength
• (wave)speed = frequency × wavelength
