The diagram below shows two identical prisms A and B placed with their faces parallel to each other. A ray of light of single colour PQ is incident at the face of the prism A. Complete the diagram to show the path of the ray till it emerges out of the prism B.
[Hint: The emergent ray out of the prism B will be parallel to the incident ray PQ]
What should be the angle of incidence for a ray of light which suffers minimum deviation of 36° through an equilateral prism?[ Hint — A = 60° and i = ( A + δmin ) / 2 ]
An object when placed in a denser medium and is viewed from a rarer medium appears to be at a lesser depth than real death. This is because of :
- reflection
- refraction
- dispersion
- diffraction
