MCQ
The dimensional formula of wave number is
- A${M^0}{L^0}{T^{ - 1}}$
- ✓${M^0}{L^{ - 1}}{T^0}$
- C${M^{ - 1}}{L^{ - 1}}{T^0}$
- D${M^0}{L^0}{T^0}$
✓
Answer
Correct option: B.
${M^0}{L^{ - 1}}{T^0}$
b
(b) Wave number = $\frac{1}{\lambda }$
(b) Wave number = $\frac{1}{\lambda }$
$⇒$ dimension is $[{M^0}{L^{ - 1}}{T^0}]$
