an interference pattern was made by using red light. if the red light changes with blue light, the fringew will become 1) wider 2) narrower 3) fainter 4)brighter

if red light is changed by blue light , the fringe separation  will become narrower as compared to red light because wavelength of red light is longer than blue light . so longer the wavelength, greater is the fringe separation.

In Young's double slit experiment, the two slits are separated by 0.28mm and the screen is placed at a distance of 1.4m away from the slits. the distance between the centre fringe and the fifth dark fringe is measured to be 1.35cm . calculate the wavelength of light used. Also find the fringe width if the screen is moved 0.4m towards the slits, for the same experiment set up.

A parallel beam of light of wavelength 600 nm is incident normally on a slit of width 0.2 mm. If the resulting diffraction pattern is observed on a screen 1 m away, find the distance of (i) First minimum, and (ii) Second maximum, from the central maximum.

if separation between the two slits is increased till fringes are observed then what will happen to angular separation of fringes (my thought is here  fringes are not observed  and they are increasing till fringes show up ...so until then what will happen to angular width if we increase d-slit separation..does angular width increases or remains same
