Part Three Wave Notes Quiz

What is a characteristic feature of longitudinal waves?

• They can travel through a vacuum.

• They have crests and troughs.

• They require a medium to travel through.

• They are always electromagnetic.

Which of the following describes constructive interference?

• When two waves meet and their amplitudes subtract from each other.

• When two waves meet and their amplitudes add together, resulting in a larger amplitude.

• When two waves meet and cancel each other out completely.

• When two waves meet and form a standing wave.

If two waves of equal amplitude and frequency are in phase, what type of interference occurs?

• Destructive interference

• Constructive interference

• No interference

• Partial interference

What happens to the amplitude of a wave when it undergoes destructive interference?

• The amplitude increases.

• The amplitude decreases.

• The amplitude remains unchanged.

• The wave disappears completely.

Which of the following conditions is necessary for two waves to interfere constructively?

• They must have different frequencies.

• They must be out of phase.

• They must have the same amplitude.

• They must be in phase.

In which direction does a transverse wave move relative to the direction of the disturbance?

• Parallel to the disturbance

• Perpendicular to the disturbance

• In a circular motion

• In a random direction

Which of the following is a characteristic of longitudinal waves?

• They can travel through a vacuum

• They have crests and troughs

• They require a medium to travel

• They are transverse waves

What is the result when two waves of the same frequency and opposite phase meet?

• Constructive interference

• Destructive interference

• No interference

• Amplification

Which of the following phenomena is a characteristic of longitudinal waves?

• The transmission of sound in a medium

• The movement of water in a river

• The vibration of strings in a guitar

True or False Transverse waves can travel through  space as well as a medium.
