A double-slit interference experiment is performed with blue-green light from an argon-gas laser. The separation between the slits is 0.50 mm, and the first-order maximum of the interference pattern is at an angle of 0.059° from the center of the pattern. What is the wavelength of argon laser light, in nanometers?

Explanation:

The angular position of first order maximum = λ /d where λ is wavelength and d is slit separation

.059⁰ = ( π / 180 ) x .059 radian

= 1.02922 x 10⁻³ radian .

Given

1.02922 x 10⁻³  =  λ /d

λ = d x 1.02922 x 10⁻³

= .5 x 10⁻³ x 1.02922 x 10⁻³

= .51461 x 10⁻⁶ m

= 514.61 x 10⁻⁹ m

= 514.61 nm .

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
