Question

A source x of unknown frequency produces 8 beats with a source of 250 Hz and 12 beats with a source of 270 Hz. The frequency of source X is (A) 258 Hz (B) 242 Hz (C) 262 Hz (D) 282 Hz

Beats per second =|v x -v y | So from the first condition, we get vx=258 Hz or 242 Hz So from the first condition, we get vx=258 Hz or 282 Hz Thus frequency is 258 Hz.

Q. A source x of unknown frequency produces 8 beats with a source of 250 Hz and 12 beats with a source of 270 Hz. The frequency of source X is

282 Hz

Beats per second $= ∣ v_{x} - v_{y} ∣$
So from the first condition, we get $v_{x} = 258 Hz$ or $242 Hz$
So from the first condition, we get $v_{x} = 258 Hz$ or $282 Hz$
Thus frequency is $258 Hz$ .

Beats per second =∣vx​−vy​∣ So from the first condition, we get vx​=258Hz or 242Hz So from the first condition, we get vx​=258Hz or 282Hz Thus frequency is 258Hz.
