A source of sound of frequency `f_1` is placed on the ground. A detector placed at a height is released from rest on this source. The observed frequency `f(Hz)` is plotted against time `t(sec)` . The speed of sound in air is `300(m)/(s)`. Find `f_1` (`g=10(m)/(s)`).

A

`0.5xx10^(3)Hz`

B

`1xx10^(3)Hz`

C

`0.25xx10^(3)Hz`

D
