Parts of a Wave

What is the definition of amplitude in a wave?

• Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

• Amplitude refers to the speed at which a wave travels through a medium.

• Amplitude is the frequency of the wave measured in hertz.

• Amplitude is the total energy carried by the wave.

What is the formula for calculating wave speed?

• v = frequency (f) × wavelength (λ)

• v = wavelength (λ) / frequency (f)

• v = frequency (f) + wavelength (λ)

• v = frequency (f) - wavelength (λ)

What is the significance of wave frequency?

• Frequency indicates how many waves pass a given point in one second, measured in hertz (Hz).

• Frequency is the measure of the amplitude of a wave.

• Frequency determines the speed of sound in a medium.

• Frequency is the distance between two consecutive peaks of a wave.

What is the difference between transverse and longitudinal waves?

• In transverse waves, the particle displacement is parallel to the direction of wave propagation, while in longitudinal waves, the displacement is perpendicular to the direction of wave propagation.

• In transverse waves, the particle displacement is perpendicular to the direction of wave propagation, while in longitudinal waves, the displacement is parallel to the direction of wave propagation.

• Transverse waves can travel through solids only, while longitudinal waves can travel through both solids and liquids.

• Transverse waves have a higher frequency than longitudinal waves.

What is a crest in a wave?

• The lowest point of a wave, representing the minimum displacement of the wave from its rest position.

• The highest point of a wave, representing the maximum displacement of the wave from its rest position.

• A point where the wave begins to break and form foam.

• The distance between two consecutive crests of a wave.

What is the role of a medium in wave propagation?

• A medium is the substance through which a wave travels, and it can be solid, liquid, or gas.

• A medium is the energy source that generates the wave.

• A medium is the frequency at which the wave oscillates.

• A medium is the distance the wave travels before it dissipates.

What is constructive interference in waves?

• Constructive interference occurs when two waves meet and combine to produce a wave of greater amplitude.

• Constructive interference occurs when two waves cancel each other out, resulting in a wave of lower amplitude.

• Constructive interference occurs when waves travel in opposite directions, creating a standing wave.

• Constructive interference occurs when waves are out of phase, leading to destructive interference.

How do you identify the amplitude on a wave diagram?

• The amplitude is the horizontal distance between two consecutive crests.

• The amplitude is the vertical distance from the rest position to the crest or trough of the wave.

• The amplitude is the total height of the wave from crest to trough.

• The amplitude is the frequency of the wave measured in Hertz.

What is the relationship between wavelength and frequency?

• Wavelength and frequency are directly related; as the wavelength increases, the frequency also increases.

• Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

• Wavelength and frequency are unrelated; changes in one do not affect the other.

• Wavelength and frequency are equal; they have the same numerical value.

How is amplitude measured?

• From the rest position to the crest or trough of the wave.

• From the peak of the wave to the next peak.

• From the trough to the next trough.

• From the rest position to the midpoint of the wave.
