A student is observing a diagram showing the path of a ray of light passing through a glass prism. He would find that for all angles of incidence the ray of light bends:
Draw a ray diagram to show the dispersion of white light.
In the figure given alongside, a narrow beam of white light is shown to pass through a triangular glass prism. After passing through the prism, it produces a spectrum YX on the screen.
Why do different colours of white light bend through different angles with respect to the incident beam of light?
How could you show that the colours of the spectrum combine to give white light?
Name the process which is involved in the formation of a rainbow.
A beam of white light is shone onto a glass prism. The light cannot be:
(a) deviated
(b) dispersed
(c) focused
(d) refracted
If white light is used in same way what change is expected in the emergent beam?
Complete the ray diagram given below to show the nature of light produced on the screen.
The completed ray diagram is as shown below:
What is the cause of the dispersion of white light through a glass prism? Draw a ray diagram to show the path of light when two identical glass prisms are arranged together in an inverted position with respect to each other and a narrow beam of white light is allowed to fall obliquely on one of the faces of the prisms.
How can the presence of ultraviolet radiation be detected?
