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 .

explanation:

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
