Waves Part I-2021

Front

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

Back

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

Front

What is the relationship between frequency and period?

Back

The period (T) is the time it takes for one complete cycle of a wave to pass a given point, and frequency (f) is the reciprocal of the period: f = 1/T.

Front

What is the unit of measurement for frequency?

Back

Hertz (Hz), which is equivalent to cycles per second.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave in which the particle displacement is perpendicular to the direction of wave propagation.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave in which the particle displacement is parallel to the direction of wave propagation.

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 energy of the wave.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement above the rest position.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, representing the maximum displacement below the rest position.

Front

How do you calculate the frequency of a pendulum if its period is known?

Back

Frequency (f) can be calculated using the formula f = 1/T, where T is the period of the pendulum.

Front

What is the formula for wave speed?

Back

Wave speed (v) can be calculated using the formula v = f × λ, where f is frequency and λ (lambda) is wavelength.
