Question

if frequency of a wave is 300hz and wave length is 10 cm . calculate velocity of wave​

Answer 1

Answer :

The required velocity of the wave is 30 m/s

Explanation :

Given :

frequency of a wave = 300 Hz

wavelength = 10 cm

To find :

the velocity of wave

Solution :

The wave speed formula which involves wavelength and frequency is given by,

   $\underline{\boxed{\bf v=n \lambda}}$

where

➙ v denotes velocity of the wave

➙ n denotes frequency of the wave

➙ λ denotes wavelength

Substituting the values,

 v = 300 Hz × 10 cm

 v = 300 Hz × (10/100) m

 v = 300 Hz × 0.1 m

 v = 30 m/s

Therefore, the velocity of the wave is 30 m/s

⇒ Wave speed is the distance a wave travels in certain time.

⇒ Waves travel fastest through solids and slowest through gases.

⇒ Units of frequency : Hz (or) sec⁻¹
