Answer:
frequency of the first tuning fork can be 274 Hz or 266 Hz
Explanation:
Given data :
we have number of beats per second = 4
thus, it can also be written as
Beat frequency of the tuning fork, v = 4 Hz
Frequency of the tuning fork, f = 270 Hz
now, the beat frequency is actually the difference of the consecutive frequency.
thus, we have
Frequency of the first tuning fork as = 270 Hz + 4 Hz = 274 Hz
or
Frequency of the first tuning fork as = 270 Hz - 4 Hz = 266 Hz
Therefore, the frequency of the first tuning fork can be 274 Hz or 266 Hz
