A light source which emits light of two wavelengths λ1=4300 Å and λ2=5100 Å, is being used in a double slit interference experiment. If the distance between the two slits is 0.025 mm and screen is at a distance 1.5 m, calculate the separation between the third order bright fringes formed due to the two wavelengths.?

Calculation of Separation between Third Order Bright Fringes due to Two Wavelengths

Given:

Wavelength λ1 = 4300 Å

Wavelength λ2 = 5100 Å

Distance between the two slits = 0.025 mm

Distance between the screen and the slits = 1.5 m


Formula:

The formula to calculate the distance between the nth order bright fringes is given by:

y = nλD/d

Where,

y = distance between the nth order bright fringes

n = order of the bright fringe

λ = wavelength of light

D = distance between the screen and the slits

d = distance between the two slits


Calculation:

First, we need to calculate the distance between the third order bright fringes for both wavelengths separately. Using the above formula, we get:

For λ1:

y1 = 3 x 4300 Å x 1.5 m / 0.025 mm = 0.77 m

For λ2:

y2 = 3 x 5100 Å x 1.5 m / 0.025 mm = 0.91 m


The separation between the third order bright fringes is given by the difference between y2 and y1:

Separation = y2 - y1 = 0.91 m - 0.77 m = 0.14 m


Therefore, the separation between the third order bright fringes formed due to the two wavelengths is 0.14 m.
