Question

If the speed of a wave is 340 m/s and its frequency is 2000 Hz, then the
wavelength of the wave will be:​

Answer 1

0.17 m

Explanation:

Given:

• Velocity of a wave = 340 m/s
• Frequency = 2000 Hz

To find:

• Wavelength of the wave.

Formulae applied:

The relation between frequency, velocity and wavelength is given below:

⇒ μ = v/λ

⇒ λ = v/μ

Here,

• μ = Frequency

• v = Velocity

• λ = Wavelength

Solution:

Let us directly apply the formula to find the wavelength of the wave.

⇒ λ = v/μ

⇒ λ = 340/2000

⇒ λ = 0.17 m

Hence, the wavelength of the wave is 0.17 m.
