When monochromatic light of wavelength 430 nm is incident on a double slit of slit separation 5 μm, there are 11 interference fringes in its central maximum. How many interference fringes will be in the central maximum of light of wavelength 632.8 nm for the same double slit?
A double slit produces a diffraction pattern that is a combination of single- and double-slit interference, where the first minimum of the single-slit pattern falls on the fifth maximum of the double-slit pattern. Find the ratio of the width of the slits to the distance between the slits.
White light falls on two narrow slits separated by 0.40 mm. The interference pattern is observed on a screen 3.0 m away.
What is the separation between the first maxima for red light and violet light ?
At what point nearest the central maximum will a maximum for yellow light coincide with a maximum for violet light ?
What orders of maxima of yellow light and violet light will coincide nearest the central maximum?
