Diffraction Patterns and Interference (HSC SSCE Physics): Flashcards

Reflection, refraction, diffraction, interference

$\delta = d\sin\theta$

$d\sin\theta = m\lambda$

$d\sin\theta = (m + \frac{1}{2})\lambda$

$a\sin\theta = m\lambda$ (m = ±1, 2, 3, ...)

Produces wider diffraction pattern

$N = 2m - 1$ where $m = \frac{d}{a}$

$d\sin\theta = m\lambda$

Counts fringes from central maximum (m = 0, 1, 2, ...)

Produces sharper, thinner maxima
