Dimensional Formula of Power of Lens
The dimensional formula of Power of Lens is given by,
M0 L-1 T0
- M = Mass
- L = Length
- T = Time
Power of Lens (D) = Focal Length-1 . . . (1)
The dimensional formula of focal length = [M0 L1 T0] . . . . (2)
On substituting equation (2) in equation (1) we get,
Power of Lens = Focal Length-1
Or, D = [M0 L1 T0]-1 = [M0 L-1 T0].
Therefore, the power of lens is dimensionally represented as [M0 L-1 T0].
