IGCSE U6 and U7 waves

Transversal or longitudinal waves refer to the:

• a) Direction of particle displacement relative to the direction of wave propagation
• b) Speed of wave propagation
• c) Wavelength of the wave
• d) Frequency of the wave

The formula to calculate wave propagation velocity is:

• a) v=fλ
• b) v=λf​
• c) v=fλ​
• d) v=f+λ

Frequency or pitch refers to the:

• a) Height of the wave
• b) Rate of vibration of the wave
• c) Speed of the wave
• d) Direction of the wave

Timbre refers to the:

• a) Loudness of the wave
• b) Quality or tone color of the wave
• c) Speed of the wave
• d) Wavelength of the wave

Wavelength is the distance between:

• a) Two consecutive crests or troughs of a wave
• b) The top and bottom of a wave
• c) The peak and the midpoint of a wave
• d) The start and end points of a wave

Amplitude or volume refers to the:

• a) Height of the wave
• b) Rate of vibration of the wave
• c) Quality or tone color of the wave
• d) Loudness of the wave

A ripple tank is a device used to demonstrate:

• a) Reflection of light waves
• b) Refraction of light waves
• c) Diffraction of water waves
• d) Interference of sound waves

The formula to calculate the period of a wave is:

• a) T=f1​
• b) T=fλ
• c) T=λf​
• d) T=λ

Reflection refers to the:

• a) Bending of waves as they pass through a medium
• b) Change in direction of waves when they pass from one medium to another
• c) Bouncing back of waves when they encounter a boundary
• d) Spreading out of waves as they pass through an opening

Refraction occurs when waves:

• a) Bounce back after hitting a surface
• b) Bend as they pass through different mediums
• c) Spread out after passing through an opening
• d) Interfere with each other constructively or destructively
