Question

the distance between four consecutive rarefaction of a sound wave is 9 cm, then the wavelength of the wave is?

Answer 1

Wavelength will be equal to 4.5 cm

Explanation:

We have given distance between 4 consecutive rarefaction of sound is 9 cm

We have to find the wavelength

Wavelength is the distance between two consecutive rarefaction but here we have given distance between 4 consecutive rarefaction so we have to divide by 2

So in this case wavelength will be equal to $=\frac{9}{2}=4.5cm$

So wavelength will be equal to 4.5 cm

Answer 2

Answer:

kindly find the following attachment

Explanation:

here there a three waves

so

$3x = 9cm$

$x = \frac{9}{3} cm$

$x = 3cm$
