Small Angle Approx - do3
Change in magnitude from flux ratio.
It's not because of the multiple slits in the grating, but because the slits are much closer together than young's slits.
Letβs start with π¦ = π₯ s i n and compare it to.

When we were able to derive until the part where $n \lambda =a \sin(\theta)$, we need to apply small angle approximation and get to $n \lambda =a \tan(\theta)$.
(d) distance from size and angle.
Now everyone also knows that the small angle approximation for $\cos$ is just the truncated ($o(\theta^3)$) taylor series, and it's fairly easy to see that for small $\theta$:
