State the phenomena observed in the above diagram. Explain with reference to the
diagram, which of the two lights mentioned above will have the higher wavelength?
The diagram shows the phenomenon called Dispersion of Light through a glass prism .
- Dispersion of light is the phenomenon of splitting white light into its component colours when passed through a transparent medium.
- White light is split into 7 colours in decreasing order of their wavelengths and/or velocity from top to bottom when passed through a glass prism.
Therefore, Yellow light has a higher wavelength than Blue light .
