Question

Why do coloured fringes appear with white light and no filter?

पर्याय

• The pattern is indistinct or disappears

• Different wavelengths produce maxima at different positions

• Red light and blue light have the same wavelength

• The slit is not parallel to the filament

Answer 1

White light contains different wavelengths. They produce maxima at different positions, making coloured fringes visible.
