Waves 2 - characteristics

Front

What is the definition of frequency 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

How is wavelength defined in wave physics?

Back

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

Front

What is amplitude in relation to waves?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa, according to the wave equation: v = fλ.

Front

What does a higher frequency indicate about a wave's energy?

Back

A higher frequency indicates that the wave carries more energy, as energy is directly proportional to frequency.

Front

What is the period of a wave?

Back

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

Front

How do you calculate the speed of a wave?

Back

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

Front

What is the significance of wave interference?

Back

Wave interference occurs when two or more waves overlap, resulting in a new wave pattern that can be constructive (amplitude increases) or destructive (amplitude decreases).

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves have oscillations perpendicular to the direction of wave travel (e.g., light waves), while longitudinal waves have oscillations parallel to the direction of wave travel (e.g., sound waves).

Front

What is a standing wave?

Back

A standing wave is a wave that remains in a constant position, formed by the interference of two waves traveling in opposite directions.
