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}] $
