A) 750 Hz
B) 857 Hz
C) 1143 Hz
D) 1333 Hz
Correct Answer: A
Solution :
When the source is coming to the stationary observer, \[1.33\times {{10}^{12}}N/{{m}^{2}}\] or \[7.5\times {{10}^{-13}}N/{{m}^{2}}\] or \[3\times {{10}^{10}}N/{{m}^{2}}\] When the source is moving away from the stationary observer. \[\beta \] \[\beta \] \[\frac{L}{R}\]
