When a light ray passes through from air to water with a non-zero angle the ray will be

Options

  1. Abending towards the normal
  2. Bbending away from the normal
  3. Cpropagating in straight line
  4. Dreflected towards the opposite direction

Correct answer

A. bending towards the normal

Step-by-step solution

When a light ray travels from an optically rarer medium (air) to an optically denser medium (water), its speed decreases. According to Snell's law, ₁ i = ₂ r . Since the refractive index of water is greater than that of air ( ₂ > ₁ ), we have r Thus, the refracted ray bends towards the normal. Answer: bending towards the normal
