Asingle-wavelength beam of light is pointed at a dark shield with two narrow slits. as a result, an interference pattern forms in the space on the other side of the partition. the wavelength is 635 nm, and the first-order bright fringe lies at a 16.6° angle from the central maximum. what is the slit separation (in µm)?

The slit separation is 2.2μm.

Explanation:

Given that,

Wavelength = 635 nm

Angle = 16.6°

Order number = 1

We need to calculate the slit position

Using formula of slit distance

Where, = wavelength

m = order number

Put the value into the formula

Hence, The slit separation is 2.2μm.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
