Dimensional Formula of Power of Lens

The dimensional formula of Power of Lens is given by,

M⁰ L^-1 T⁰

Where,

• M = Mass
• L = Length
• T = Time

Derivation

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].
