Magnification, m = v/u = 30/15 =
1/10 = 1/15 + 1/v 1/v = 1/10 – 1/15 = (3 – 2)/30 = 1/30 v = 30 cm (Image distance) Magnification, m = v/u = 30/15 = 1/10
Image height = m × object height = 2 × 2 cm = Magnification, m = v/u = 30/15 = 1/10
A light ray travels from water (n = 1.33) into air. The angle of incidence in water is 35°. Calculate the angle of refraction in air. Magnification, m = v/u = 30/15 = 1/10
