Question

How can you calculate the speed of a wave?

Divide its wavelength by its frequency.
Divide its amplitude by its frequency.
Multiply its wavelength by its amplitude.
Multiply its wavelength by its frequency.

Answers

You can calculate the speed of a wave by multiplying its wavelength by its frequency. The formula for calculating the speed of a wave is:

Speed (v) = Wavelength (λ) x Frequency (f)

v = λ x f

For example, if the wavelength of a wave is 2 meters and its frequency is 50 Hertz, then the speed of the wave can be calculated as:

v = 2m x 50Hz = 100 m/s

Therefore, the speed of the wave is 100 meters per second.
