Observer A is at rest. Source `S_(1)` is moving towards observer A and source `S_(2)` is moving away from observer A. velocity of sound is `330(m)/(sec)`. `beta`= beat frequency heard per second by A. Approximate value of `beta` is: |
|
Answer» Correct Answer - 2 `beta=33(330/(330-10)-330/(330+10))` `=33(330(2xx10))/((330)^(2)-(10)^(2))` then `beta=33xx20/300=2Hz` |
