Question
A ray of light in a liquid of refractive index 1.4, approaches the boundary surface between the liquid and air at an angle of incidence whose sine is 0.8. Which of the following statements is correct about the behaviour of the light
- It is impossible to predict the behavior of the light ray on the basis of the information supplied.
- The sine of the angle of refraction of the emergent ray will less than 0.8.
- The ray will be internally reflected
- The sine of the angle of refraction of the emergent ray will be greater than 0.8.
The correct answer is: The ray will be internally reflected
