A light ray does not bend at the boundary in passing from one medium to the other medium if the angle of incident is ______.
Name two factors which affect the critical angle for a given pair of media. State how do the factors affect it.
A ray of light incident at an angle of incidence ‘i’ passes through an equilateral glass prism such that the refracted ray inside the prism is parallel to its base and emerges from the prism at an angle of emergence ‘e’.
What can you say about the value of the angle of deviation in such a situation?
Choose the correct option.
Angles of deviation for extreme colours are given for different prisms. Select the one having maximum dispersive power of its material.
Explain ‘mirage’ as an illustration of refraction.
Answer the following question.
Under what conditions are total internal reflection possible? Explain it with a suitable example.
For a ray of light, the critical angle is minimum when it travels from ______.
Which of the following statements about total internal reflection is true?
The angle of incidence at which the angle of refraction is Q£ is called the critical angle.
The diagram below shows a fish in the tank and its image seen on the surface of the water.
Name the phenomenon responsible for the formation of this image.
