Question

Let's say that the red laser has a wavelength of 650 nm, the distance between the two slits is 28000 nm, and the distance between the double slit and the screen is 2.30 m. What is the distance on the screen between the center of the central maximum (m = 0) and the center of one of the fifth-order maxima?

Answer 1

The value is
`y = 0.267 \ m`

Step-by-step explanation:

From the question we are told that

The wavelength is
`\lambda = 650 \ nm = 650 *10^(-9) \ m`

The distance of separation between the two slit is
`d = 28000nm = 28000 *10^(-9) \ m`

The distance between the slit and the screen is
`D = 2.30 \ m`

Generally the path difference is mathematically represented as

`y = ( m * D * \lambda )/(d)`

Here m is the order of the fringe and the value is m = 5

So

`y = ( 5 * 2.30 * 650 *10^(-9) )/( 28000 *10^(-9))`

=>
`y = 0.267 \ m`
