Calculate the power of lens in thier corrective spectacles

Reference no: EM13554019

A long sighted person can only see clearly objects further than 1.2 m away.They wish to read a book held 30 cm away. Calculate the power (in diopters) of the lens in thier corrective spectacles: state if the lens is concave or convex and draw a ray diagram that has the appropriate image and object positions labeled.
