Question

What is the wavelength of a sound wave that has a speed of 680 m/s and a frequency of 220 Hz? (With full explanation)

Answer 1

• 3.0909 m

Step-by-step explanation:

Given,

• Wave speed = 680 m/s
• frequency = 220 Hz

We need to find the wavelength of sound wave :

We know that ,

• 
  `{ \underline{ \boxed{ \sf{F = (v)/(\lambda)}}}}`

where,

• F is frequency,
• v is wave speed,
• 
  `\sf\lambda` is wavelength

on substituting the values we get :

`\dashrightarrow \sf \: 220 = (680)/(\lambda) \\ \\ \dashrightarrow \sf \: \lambda = (680)/(220) \\ \\ \dashrightarrow \sf \:\lambda = 3.0909 \: m\\`

Hence,

• Wavelength of sound is 3.0909 m
