Question

Light with a wavelength of 725 nm passes through the slits of a double-slit experiment. The slits of the experiment are a distance 0.0335 mm apart. What angle does the light make for the third dark fringe?

Answer 2

Answer:

Explanation:

Angle for the nth dark fringe of light = n * wavelength of light / slit distance

So the angle for the 3rd fringe = 3 * 725 nm /  0.0335 mm

= 3 * 725*10^(-9) /  0.0335*10^(-3)

= 0.0649 rad

= 0.0649 * 360 / 2pi degree

= 3.72 degree
