Assertions : A beam of white light give a spectrum on passing through a hollow prism. Reason : Speed of light outside the prism is different from the speed of light inside the prism.
A beam of white lighe passing through a hollow prism gives no spectrum.
A beam of white light passing through a hollow prism give no spectrum.
Why do components of incident white light splits into a spectrum while passing through a glass prism?
Assertion : A beam of white light when passed through a hollow prism cannot give spectrum. Reason : Because refractive index of air inside and outside the prism is same so no refraction and hence no deviation wll take place.
When a white light passes through a hollow prism then
The splitting of white light into several colours on passing through a glass prism is due to
The splitting up of white light into seven colours on passing through a glass prism is called :
