Physics And Measurement Question 93

Question: The dimensional formula of wave number is

Options:

A) $ M^{0}L^{0}{{T}^{-1}} $

B) $ M^{0}{{L}^{-1}}T^{0} $

C) $ {{M}^{-1}}{{L}^{-1}}T^{0} $

D) $ M^{0}L^{0}T^{0} $

Show Answer

Answer:

Correct Answer: B

Solution:

Wave number = $ \frac{1}{\lambda } $

dimension is $ [M^{0}{{L}^{-1}}T^{0}] $
