(c)
Coherent light that contains two wavelengths, 660 nm (red) and 470 nm (blue), passes
through two narrow slits separated by 0.3 mm, and the interference pattern is observed
on a screen 5 m from the slits. Calculate the distance on the screen between the first-
order bright fringes for red and blue light.

two identical waves arriving at a point is 0.05
cm. If wavelength of light used is 5000 Å, then
