For a wavelength of 420 nm, a diffraction grating produces a bright fringe at an angle of 24°. For an unknown wavelength, the sa
Inessa [10]

Answer:

649.8420 nm

Explanation:

We have given \Theta _1=24^{\circ} \ and\ \Theta _2=39^{\circ}

\lambda _1=420\ nm we have to find unknown wavelength that is \lambda _2

The condition for constructive interference is dsin\Theta =n\lambda

Where d is distance between slits \Theta is angle of emergence and n is order of maxima

Using constructive interference equation

dsin\Theta _1=n\lambda _1 ---------eqn 1

dsin\Theta _2=n\lambda _2---------eqn 2

On dividing eqn 1 by eqn 2

\frac{\lambda _1}{\lambda _2}=\frac{sin\Theta _1}{sin\Theta _2}

\frac{420}{\lambda _2}=\frac{sin24^{\circ}}{sin39^{\circ}}

\lambda _2=649.8420\ nm
