Answer:
frequency= 165Hz
period=
Step-by-step explanation:
1. To calculate the frequency using the formula:
f = v/λ
where,
f=frequency (what the question asked)
v=speed of wave (given in the question=330m/s)
λ=wavelength (given in the question=2m)
SO,
= 165Hz
2. To calculate the period use the formula:
since
therefore,
where,
f= frequency (what we solved above=165Hz)
T= period (what the question asked)
SO,
