Equations from last 3rd of quarter.
(See previous equation reviews for comprehensive portion.)


35.4
Index of refraction: $n= \frac{c}{v}$
35.7
Wavelength in medium with index of refraction n: $\lambda_n = \frac{\lambda}{n} $

Sign conventions for spherical mirrors
36.8
Spherical refracting surfaces: $ \frac{n_1}{p}+\frac{n_2}{q} = \frac{n_2 - n_1}{R} $

36.17
Two thin lenses in contact have net focal length: $\frac{1}{f} = \frac{1}{f_1} + \frac{1}{f_2}$

37.1
Path length difference, double slit with slit separation d:   $\delta = d\sin \theta$
37.2
Constructive interference by double slit:

\begin{displaymath}\delta = d\sin \theta_{bright} = m\lambda ~~~ (m=0,\pm 1,\pm 2, ...)\end{displaymath}

37.3
Destructive interference by double slit:

\begin{displaymath}d\sin \theta_{dark} = (m+\frac{1}{2})\lambda ~~~ (m=0,\pm 1,\pm 2, ...) \end{displaymath}

37.4
Double slit pattern: the position of P on wall is $y$ above the central maximum, where
$\frac{y}{L} = \sin \theta$
37.15
