Question

A speaker emits sound of freequency f Hz and another speaker emits sound of freequency 2f Hz compare the welvelength of the two sound waves

Answer 1

Answer:

let sound speed be y and wavelength be x

f=yx(speed× wavelength

as

2f=yx'

wavelength and speed only should change as in different medium but here it's in same medium so speed of sound is same

f=yx'/2

x/x'=1/2
