The power of lens is

P = \frac{1}{f},\;

where f is focal length of the lens . The dimensions of power of lens are

View answer and explanation

Correct option: B

\left[ {{\mathrm{M}^0}{\mathrm{L}^{ - 1}}{\mathrm{T}^0}} \right]

Option B ([M⁰L⁻¹T⁰]) is correct because power of a lens is the reciprocal of focal length, which has the dimension of length.
