Question

In a double-slit experiment using light of wavelength 486 nm, the slit spacing is 0.600 mm and the screen is 2.00 m from the slits. Find the distance along the screen between adjacent bright fringes.

Answer 1

The distance is
`y = 0.00162 \ m`

Step-by-step explanation:

From the question we are told that

The wavelength is
`\lambda = 486 \ nm = 486 *10^(-9) \ m`

The slit spacing is
`d = 0.600 \ mm = 0.60 *10^(-3) \ m`

The distance of the screen is
`D = 2.0 \ m`

Generally the distance along the screen between adjacent bright fringes is mathematically represented as

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

substituting values

`y = ( 486 *10^(-9) * 2)/(0.6*10^(-3))`

`y = 0.00162 \ m`
