6C - Sound Diffraction & Interference

Front

What is the definition of wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

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 longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's propagation.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's propagation.

Front

What is frequency in the context of waves?

Back

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

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

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to form a wave with a larger amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to form a wave with a smaller amplitude or cancel each other out.

Front

What is the formula for calculating wave speed?

Back

Wave speed (v) = frequency (f) × wavelength (λ).

Front

What is the period of a wave?

Back

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