Answer the case-based question given below
Light of all the colours travel at the same speed in vacuum for all wavelengths. But in any transparent medium(glass or water), the light of different colours travels at different speeds for different wavelengths, which means that the refractive index of a particular medium is different for different wavelengths. As there is a difference in their speeds, the light of different colours bend through different angles.
The speed of violet colour is maximum and the speed of red colour is minimum in glass so, the red light deviates least and violet colour deviates most.
Hence, higher the wavelength of a colour of light, smaller the refractive index and less is the bending of light.
Read the above passage carefully and give the answer of the following questions:
The speed of violet colour is maximum and the speed of red colour is minimum in glass so, the red light deviates least and violet colour deviates most.
Hence, higher the wavelength of a colour of light, smaller the refractive index and less is the bending of light.
