What will happen if we replaced sodium lamp to white source in newton ring experiments?

Answer 1

if white light is used in place of monochromatic light, a few coloured rings are observed. each colour gives rise to its own system snd it gives a rainbow type illuminetion. tjese rings soon superimpose and result in uniform illumination

Answer 2

I'll speculate. White light is a mix of many wavelengths. Just like a prism, the white light may be separated into multiple 'colored' rings which would probably overlap because of the small distances involved in the experiment. Yellow is closer to a single wavelength eliminating the 'rainbow effect' which might occur from using white light.

Answer 3

Instead bright and dark rings we get only coloured rings

Answer 4

sodium lamp gives you a monochromatic light .Mercury light&white is mixture of all seven colours

Answer 5

It would evaporate
