Question

a stationary wave of fundamental frequency has a frequency of 120 hz has been generated in a medium calculate three lighter frequency at which stationary waves could be produced

Answer 1

The rule is

`\boxed{\sf \\u _n=n\\u_1}`

So

For n=1

`\\ \rm\Rrightarrow \\u_1=1(120)=120Hz`

For n=2

`\\ \rm\Rrightarrow \\u_2=2(120)=240Hz`

for n=3

`\\ \rm\Rrightarrow \\u_3=3(120)=360Hz`

Answer 2
