What is the definition of frequency?

Back

Frequency is the number of cycles or oscillations that occur in a unit of time, typically measured in Hertz (Hz).

Front

What is the definition of period?

Back

The period is the time taken for one complete cycle of a wave or oscillation, measured in seconds.

Front

How are frequency and period related?

Back

Frequency and period are inversely related; as frequency increases, the period decreases, and vice versa. The relationship is given by the formula: Frequency (f) = 1 / Period (T).

Front

If a wave has a frequency of 5 Hz, what is its period?

Back

0.2 seconds (T = 1/f = 1/5).

Front

What unit is frequency measured in?

Back

Hertz (Hz).

Front

What happens to the period of a wave as frequency increases?

Back

The period decreases.

Front

What is the frequency of a wave with a period of 0.25 seconds?

Back

4 Hz (f = 1/T = 1/0.25).

Front

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

Back

Period (T) = 1 / Frequency (f).

Front

What is the relationship between wavelength, frequency, and wave speed?

Back

Wave speed (v) = Frequency (f) × Wavelength (λ).

Front

What is the definition of amplitude in the context of waves?

Back

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