In Youngs double slit experiment, sodium light composed of two wavelengths \lambda_1 and \lambda_2 close to each other (with \lambda_2 greater than \lambda_1) is used. The order n up to which the fringes can be seen on the screen is given by

Correct Answer is : n = λ22(λ2−λ1)

n = \lambda_2/{\lambda_2-\lambda_1}

n = \lambda_1/{\lambda_2-\lambda_1}

n = \lambda_2/{2(\lambda_2-\lambda_1)}

n = \lambda_1/{2(\lambda_2-\lambda_1)}

In Youngs double slit experiment, sodium light composed of two wavelengths λ1 and λ2 close to each other (with λ2 greater than λ1) is used. The order n up to which the fringes can be seen on the screen is given by

n =
λ2
λ2−λ1
n =
λ1
λ2−λ1
n =
λ2
2(λ2−λ1)
n =
λ1
2(λ2−λ1)
