(d) green
A ray of light moving from an optically rarer to a denser medium
The diagram below shows the path taken by a narrow beam of yellow monochromatic light passing through an equiangular glass prism. If the yellow light is replaced by a narrow beam of white light incident at the same angle, draw another diagram to show the passage of white light through the prism and label it to show the effect of prism on the white light.
A glass prism is able to produce the spectrum when white light passes through it, but a glass slab doesn’t produce any spectrum. Explain why it is so.
A wave has wavelength 50Å of State the speed in vacuum.
Differentiate between a glass slab and a glass prism.
State two properties of ultra-violet radiations which differ from visible light.
Write the range of wavelength of the infrared spectrum.
The splitting of white light into its component colours is called ____________.
