1.

make a diagram to show how hypermetropia is corrected. the near point of a hypermetropic eye is 1 m.what is the power of the lens required to correct this defect .assume that the near point of the normal eye is 25 CM

Answer»

⭐⭐hey mate!


To FIND the FOCAL LENGTH apply the formula


F = (N.P)(D) / N.P -D


Where ,

N.P = near point


D = least distance


1/F = 1/v -1/u


1/F = 1/-100 - 2/-25


F =100/3


Power = 3/100 × 100 = 3D
