A Young's interference experiment is performed with blue-green laser light. The separation between the slits is 0.500 mm, and the screen is located 3.14 m from the slits. The first bright fringe is located 3.24 mm from the center of the interference pattern. What is the wavelength of the laser light?

Wavelength of laser light will be

Explanation:

We have given distance between the slits d = 0.5 mm =

Distance between screen and slits D = 3.14 m

Distance of bright fringe from center

It is known that

It is also know that , here m = 1 for first bight fringe.

So wavelength of laser light will be

true

explanation:

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
