If smoke is present in between the screen and slit in Young's double slit experiment using laser, will there be any change in the interference pattern? Will the fringes be obtained on the screen?
Smoke has large particles in it and I think they can diffract light because smoke particles have sizes comparable to wavelength of light. Also, the smoke will have a different refractive index and hence can change the optical path of light which will affect the fringe pattern.
