Question

Can white light, split by one prism, be further split by using another prism?

Answer 1

white light splits into colours as that of rainbow

Answer 2

First of all white light is combination of 7 colors of different properties like wavelength frequency etc., so when we split white light all the colors are seen on the other side of the prism and when we're keep another prism same as the position of first prism all the seven colours only get refracted and you can see those colors from the other side of second prism.
