Question

The speed of a wave is 65 m/s. If the wavelength is 0.8 meters, what is the frequency of the wave?

Answer 1

Given:-

• Speed of wave ,s = 65m/s

• Length of wavelength , λ = 0.8

To Find:-

• Frequency ,F

Solution:-

As we know that

•Speed = Wavelength × Frequency

→ S = λ ×F

→ F = S/λ

Substitute the value we get

→ F = 65/0.8

→ F = 65×10/8

→ F = 650/8

→ F = 81.25m

Therefore, the frequency of the wave is 81.25 metres.

Answer 2

Answer:

81.25

Explanation:

To calculate the frequency, we need to move the decimal point, So we multiply both numbers with 10
