A wave has a distance between its peaks of 0.4 meters at a speed of 10 meters per second. What is the wave's frequency, in hertz?

25Hz

Explanation:

Given that:

Wavelength (λ) = 0.4m (the distance between the peaks of a wave is known as wavelength)

Frequency F = ?

Speed of wave V = 10 m/s

The wave frequency is the number of cycles which the wave complete in one second. It is measured in hertz, and represented by the symbol F

So, apply the formula V = F λ

10m/s = F x 0.4m

F = 10m/s / 0.4m

F = 25Hz

Thus, the frequency of the wave is 25 Hertz.

it about 600 mph from what i calculated

conduction, convection, radiation
