8 - Mechanical Waves

Front

What is the definition of Wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as from crest to crest or trough to trough.

Front

What does Amplitude represent in a wave?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

Front

What is a Crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement above the rest position.

Front

What is a Trough in a wave?

Back

A trough is the lowest point of a wave, representing the maximum displacement below the rest position.

Front

How is Frequency defined in the context of waves?

Back

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

Front

What is the relationship between Wavelength and Frequency?

Back

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

Front

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

Back

The speed of a wave (v) can be calculated using the formula: v = frequency (f) × wavelength (λ).

Front

What does the term 'Wave Period' refer to?

Back

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

Front

What is the difference between Transverse and Longitudinal waves?

Back

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

Front

What is an example of a Transverse wave?

Back

An example of a transverse wave is a wave on a string or electromagnetic waves such as light.
