| Aim - To
compare the spectra produced when the light passes through (a) a prism
and (b) a grating |
Instructions |
| |
|
|
- Observe the spectrum produced when white light is refracted through
the prism.
|
- List the colours in order, from the one that is deviated the most
to the one that is deviated least.
|
- Observe the pattern produced when white light passes through the
grating.
|
- Note the colour of the central (zero order) maximum and the order
of the colours in the other maxima produced.
