Physics Waves Review

Front

What is the definition of a wave period?

Back

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

Front

How do you calculate the frequency of a wave?

Back

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

Front

What is the formula for wave speed?

Back

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

Front

What is the third harmonic of a string fixed at both ends?

Back

The third harmonic frequency is three times the fundamental frequency, and the wavelength is two-thirds the length of the string.

Front

What is constructive interference?

Back

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

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet out of phase, resulting in a wave of reduced amplitude.

Front

What is wavelength?

Back

Wavelength (λ) is the distance between successive crests or troughs of a wave, typically measured in meters.

Front

What is the Doppler effect?

Back

The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

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 the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 m/s.
