What is a longitudinal wave?

Back

A longitudinal wave is a type of wave in which the oscillation of the medium is parallel to the direction of the wave's travel.

Front

What is the formula to calculate frequency?

Back

Frequency (f) is calculated using the formula: f = speed (v) / wavelength (λ).

What is the speed of sound in water?

Back

The speed of sound in water is approximately 233 m/s.

Front

How do you calculate the frequency of a wave if you know the speed and wavelength?

Back

Use the formula: Frequency (f) = Speed (v) / Wavelength (λ).

Front

What is amplitude in the context of waves?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles and openings, leading to interference patterns.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is the unit of frequency?

Back

The unit of frequency is Hertz (Hz), which represents one cycle per second.

Front

What happens to the speed of sound in different mediums?

Back

The speed of sound varies in different mediums; it travels fastest in solids, slower in liquids, and slowest in gases.
