A) 0.42 Hz
B) 2.75 Hz
C) 1.79 Hz
D) 0.56 Hz
E) 3.5 Hz
Correct Answer: C
Solution :
Time Taken by the wave to travel a distance equal to one wavelength \[=0.14\times 4\] \[=0.56s\] Frequency \[{{f}_{c}}=\frac{I}{T}\] \[=\frac{1}{0.56}\] \[f=\frac{100}{56}\] Or \[f=1.79\,Hz\]You need to login to perform this action.
