Amplitude, Wavelength, and Frequency

Front

What is the definition of amplitude in a wave?

Back

Amplitude is the height of a wave, representing the amount of energy carried by the wave. In a transverse wave, it is the distance from the baseline to the crest or trough.

Front

What does wavelength refer to in a wave?

Back

Wavelength is the distance between one point on a wave and the nearest point just like it, such as from crest to crest or trough to trough.

Front

Define frequency in the context of waves.

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

True or False: Amplitude affects the loudness of a sound wave.

Back

True. Higher amplitude means a louder sound.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa.

Front

How is the period of a wave defined?

Back

The period of a wave is the time it takes for one complete wave to pass a given point, measured in seconds.

Front

What happens to the energy of a wave as its amplitude increases?

Back

As the amplitude increases, the energy carried by the wave also increases.

Front

What is the formula to calculate the speed of a wave?

Back

The speed of a wave can be calculated using the formula: Speed = Frequency x Wavelength.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the motion of the medium is perpendicular to the direction of the wave's travel, such as in water waves.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the motion of the medium is parallel to the direction of the wave's travel, such as in sound waves.
