Question

What are dimension of frequency and momentum ?​

Answer 1

Answer:

Dimension of momentum = $M^{2} T^{-1}$

Dimension of frequency = $T^{-1}$

Explanation:

Dimension of momentum

h = m x v

• h is momentum
• m is mass of object
• v is velocity

In terms of dimension : m = [M], v = [M /T]

h = [M] [M /T]

  = [$M^{2} T^{-1}$]  (dimension of momentum)

Dimension of frequency

υ = 1 /t

where

• υ is frequency

• t is time period

In terms of dimension : t = [T]

υ = 1 /[T]

  = $T^{-1}$
