What is the wave equation?

Back

The wave equation is a mathematical description of how waves propagate through a medium, typically expressed as v = fλ, where v is the wave speed, f is the frequency, and λ (lambda) is the wavelength.

How does tension in a medium affect wave speed?

Back

Increasing the tension in a medium (like a spring or string) increases the speed of the wave.

Front

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

Back

The relationship is given by the equation v = fλ, where v is wave speed, f is frequency, and λ is wavelength.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

How do you calculate the speed of a wave given its frequency and wavelength?

Back

The speed of a wave can be calculated using the formula v = fλ, where v is speed, f is frequency, and λ is wavelength.

Front

What is the unit of frequency?

Back

The unit of frequency is Hertz (Hz), which represents cycles per second.

Front

If a wave has a frequency of 5 Hz and a speed of 25 m/s, what is its wavelength?

Back

The wavelength can be calculated using the formula λ = v/f, which gives λ = 25 m/s / 5 Hz = 5 m.

Front

What happens to the wavelength if the frequency of a wave increases while the speed remains constant?

Back

If the frequency increases while the speed remains constant, the wavelength decreases.

Front

What is the formula to find the wavelength of a wave?

Back

The formula to find the wavelength is λ = v/f, where λ is wavelength, v is wave speed, and f is frequency.
