If the concave lens of focal length (f = 1.5m) used to restore the proper vision, then what is the power of lens.
Question
Solution 1
The power of a lens is given by the formula:
P = 1/f
where: P is the power of the lens, f is the focal length of the lens.
In this case, the focal length f is given as 1.5m. However, the focal length of a concave lens is taken as negative. So, f = -1.5m.
