A ray of light passes from water to air. How does the speed of light change?
Draw the diagram of refraction of light in the glass slab
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).
Which colour of light travels fastest in any medium except air?
A ray of light strikes the surface at a rectangular glass slab such that the angle of incidence is 45o.
In each case, draw diagram to show the path taken by the ray as it passes through the glass slab and emerges from it.
What is meant by the refraction of light?
A ray of light passes from water to air. How does the speed of light change?
Comment on the statement ‘The refractive index of glass is 3/2.’
