A wave has a wavelength of 10 m and a speed of 65 m/s. What is the frequency of this wave in Hz?

Frequency is the number of wave passing through a certain point per unit time. The frequency of the given wave is 6.5 Hz.

Frequency:

It is the rate of wave oscillation per unit time. It is measure in Hertz. One Hertz is equals to a wave passing from a point in 1 second.

Frequency of the wave can be calculate by the formula,

Where,

V - speed of the wave =  65 m/s

f - Frequency = ?

- wavelength = 10 m

put the values in the formula and calculate it for f,

Therefore. the frequency of the given wave is 6.5 Hz.

f = 6.5Hz

Explanation:

Given that the

Speed V = 65 m/s

Wavelength (λ) = 10m

Wave speed is the product of frequency and wavelength. That is,

V = fλ

Substitute V and (λ) into the formula to get frequency f

65 = 10f

Make f the subject of formula

f = 65/10

f = 6.5 Hz

Therefore, the frequency of this wave is 6.5 Hz?

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
