Q: If the value of the refractive index increases then:
  • A. deviation decreases
  • B. deviation in direction of light increases
  • C. there is no deviation in direction of light
  • D. light will follow curved path
Correct Answer: Option B - The higher the refractive index the slowly the light rawls, which causes a corresponding increased in the defection (refraction) upon entering or leaving the material.
B. The higher the refractive index the slowly the light rawls, which causes a corresponding increased in the defection (refraction) upon entering or leaving the material.

Explanations:

The higher the refractive index the slowly the light rawls, which causes a corresponding increased in the defection (refraction) upon entering or leaving the material.
