Web16 mrt. 2024 · Definition: It is the capacity or the ability of a lens to deviate (converge or diverge) the path of rays passing through it. A lens producing more converging or more diverging, is said to have more power. The power of a lens is related to its focal length, f by the equation: The unit for power is dioptre (D). WebAs we know, Power = 1 focal length \text{Power} = \dfrac{1}{\text{focal length}} Power = focal length 1 . Given, Power of the lens = -2.0 D. As the given power is negative hence, we can say that the lens used is concave in nature. Substituting the value of power in formula we get,
