Ifa ray of light enters from a rarer medium to a denser medium at zero angle of incidence, it would

Options

  1. Areflect back.
  2. Bgo straight.
  3. Cturn towards right.
  4. Dbend at 45^ .

Correct answer

D. bend at 45^ .

Step-by-step solution

As angle is incidence is zero so ray of light along the normal and undeviated. When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left. This behavior follows from Snell's Law. As you sawbefore, the larger angle must be in the medium having the lower index of refraction.
