Question

What are the three longest wavelengths for standing waves on a 264- cm -long string that is fixed at both ends

Answer 1

The three longest wavelengths for the standing waves on a 264-cm long string that is fixed at both ends are:

1. 5.2 meters.
2. 2.6 meters.
3. 1.7meters.

Given data:

Length of the fixed string = 264cms = 2.64 meters

The wavelength for standing waves is given by:

λ = 2L/n

where,

• λ is the wavelength
• L is the length of the string

For n = 1,

• λ = 2×2.6/1

= 5.2 meters

For n = 2,

• λ = 2×2.6/2

= 2.6 meters

For n = 3,

• λ = 2×2.6/3

= 1.7 meters
