A Doctor Has Prescribed a Corrective Lens of Power, −1.5 D. Find the Focal Length of the Lens. is the Prescribed Lens Diverging Or Converging? - Science
A doctor has prescribed a corrective lens of power, −1.5 D. Find the focal length of the lens. Is the prescribed lens diverging or converging?
Power of a lens is given by:
Power (P) =`1/f`
∴ f=-66.67 cm
Since the power is negative, the lens is of a diverging nature. Therefore, it's a concave lens.
