Question

You must have seen chandeliers having glass prisms. the light from a tungsten bulb gets dispersed while passing through these prisms and we see coloured spectrum . If we use an LED light instead of a tungsten bulb, will we able to see the same effect ? Explain​

Answer 1

this is because the angle of deviation for different colours of light are different in a prism. it is because deviation depends upon the wavelength of a particular colour of light . more is the wavelength,less is the deviation and vice versa
