Question

In Young's experiment, light of wavelength 4000 Å is used to produce bright fringes of width 0.6 mm, at a distance of 2 meters. If the whole apparatus is dipped in a liquid of refractive index 1.5, then fringe width will be(a) 0.2 mm(b) 0.3 mm(c) 0.4 mm(d) 1.2 mm

Answer 1

Explanation:

The Bright Interference Fringes Are Spaced 1.8 Mm Apart On The Viewing Screen. What Will The Fringe Spacing Be If The Light Is Changed To A Wavelength Of 400 Nm? Δy = _____mm.
