Waves Test Review

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, without transferring matter itself.

What is the difference between a crest and a trough in a wave?

Back

A crest is the highest point of a wave, while a trough is the lowest point.

Front

What does amplitude refer to in a wave?

Back

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

How does wave amplitude affect energy transfer?

Back

Higher amplitude waves transfer more energy compared to lower amplitude waves.

Front

What is the relationship between frequency and wavelength in waves?

Back

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

What is the formula for wave speed?

Back

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

Front

What are mechanical waves?

Back

Mechanical waves require a medium (solid, liquid, or gas) to travel through, such as sound waves.

Front

What are electromagnetic waves?

Back

Electromagnetic waves do not require a medium and can travel through a vacuum, such as light waves.

Front

What is the principle of superposition in wave theory?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual displacements.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet in phase, resulting in a wave of greater amplitude.
