Equation

$$\frac{I(\theta)}{I_0}=\left(\frac{\sin(u)}{u}\right)^2\cdot \left(\frac{\sin(Nv)}{\sin(v)}\right)^2 \\ u=\pi b\sin(\theta)/\lambda \\ v=\pi d\sin(\theta)/\lambda$$

Latex Code

                                 \frac{I(\theta)}{I_0}=\left(\frac{\sin(u)}{u}\right)^2\cdot \left(\frac{\sin(Nv)}{\sin(v)}\right)^2 \\
            u=\pi b\sin(\theta)/\lambda \\
            v=\pi d\sin(\theta)/\lambda

Explanation

A light ray passing through a prism is refracted twice and aquires a deviation from its original direction.

  • : is the number of slits
