Question

find the dimensional formula for frequency

Answer 1

Frequency is the defined as number of complete cycles per second.

Mathematically,
Frequency = number of vibrations/sec

Dimensional Formula of Time = M0L0T1

Putting these values in above equation we get
Dimensional Formula of Frequency = 1/ M0L0T1 = M0L0T-1

Hence,
Dimensional Formula of Frequency = M0L0T-1
SI unit of Frequency is the hertz.

Answer 2

Answer:

(frequently) =(1) / (time period)

=(1) /(T)

=(M0L0T-1)
