1.Units, Dimensions and Measurement
easy
The dimensional formula of wave number is
A${M^0}{L^0}{T^{ - 1}}$
B${M^0}{L^{ - 1}}{T^0}$
C${M^{ - 1}}{L^{ - 1}}{T^0}$
D${M^0}{L^0}{T^0}$
Solution
(b) Wave number = $\frac{1}{\lambda }$
$⇒$ dimension is $[{M^0}{L^{ – 1}}{T^0}]$
$⇒$ dimension is $[{M^0}{L^{ – 1}}{T^0}]$
