Question

Out of red light and violet light, which will have more lateral displacement?

• A. Violet light
• B. Red light
• C. Both have equal displacement
• D. Data insufficient

Answer 1

The correct option is A Violet light

The red light has a less refractive index. So, the lateral displacement is less. The violet light has a more refractive index. So, the lateral displacement is also more. Therefore, on passing through the glass slab, violet light will have more shifting.
