Draw a ray diagram to show the refraction of a monochromatic ray through a prism when it suffers minimum deviation
Draw diagrams to show the refraction of light from
- air to glass, and
- glass to air. In each diagram, label the incident ray, refracted ray, the angle of incidence
- and the angle of refraction (r).
How does the angle of minimum deviation produces by a prism change with increase in :
the refracting angle of prism?
How is the angle of emergence related to the angle of incidence when prism is in the position of minimum deviation? Illustrate your answer with help of a labelled diagram using an equilateral prism?
Fig 4.31 below shows a light ray of single colour incident normally on two prisms A and B. In each case draw the path of the ray of light as it enters and emerges out of the prism. Mark the angle wherever necessary.
A coin is places at the bottom of a beaker containing water (refractive index = 4/3) to a depth of 12 cm. By what height the coin appears to be raised when seen from vertically above?
Define the term refractive index of a medium. What do you understand by the statement 'the refractive index of glass is 1.5 for white light'?
Why upper surface of water contained in a beaker and above eye level appears silvery?
How will you verify the laws of refraction or how the refractive index of glass is determined in the laboratory?
What is lateral displacement?
