Question
A parallel beam of light falls on a convex lens. The path of the rays is shown in the figure. It follows that
1 > 2 > 2
- 1 < 2 < 2
- 1 = 2 < 2
- 1 = 2 > 2
1 > 2 > 2
1 < 2 < 2
1 = 2 < 2
1 = 2 > 2
The correct answer is: 1 = 2 < 2
Since the ray does not bend at the first face of the lens, that is, it is not refracted, m1 = m. When this ray meets the second face, it bends toward the normal to that face.
Hence m2 > m.
