Question

5. The ratio of vibrations produced by two vibrating bodies x and y in a given time is 5:9 respectively. Find the body that produces shrill sound and that produces dull sound

Answer 1

1. The ratio of vibrating bodies is:

$\frac{x}{y}=\frac{5}{9}$

or 9x = 5y

2. Thus, x vibrates more than y.

3. The body that vibrates more produced a shrill sound. Thus,x produces shrill sound and y produces dull sound.
