Light with a wavelength of 488 nm is incident on a single slit with a width of 6.23 x 10^-4 m. if the screen is 2.7 m away, what is the distance to the first antinodal line?

The distance to the first anti-nodal line is .

Explanation:

Given that,

Wavelength = 488 nm

Width

Distance D =2.7 m

We need to calculate the distance to the first anti-nodal line

Using formula of the distance for first anti-nodal line

.....(I)

Where, n = number of fringe

d = width

D = distance from the screen

=wavelength of light

Put the all value in the equation (I)

Hence, The distance to the first anti-nodal line is .

attach the statements so i can answer : )
