Resource summary

Question	Answer
Frequency is the inverse of the period	f = $\frac{1}{T}$
The wave equation	V = f $\lambda$
Intensity =	$\frac{Power}{Area}$
Intensity is	∝ $(Amplitude)^2$
Refractive Index =	$\frac{Cmedium1}{Cmedium2}$ = $\frac{sini}{sinr}$
Refractive Index of material	n= $\frac{Cvacuum}{Cmaterial}$
Snell's Law	n1 $\sin$ $\theta$ 1 = n2 $\sin$ $\theta$ 2
Line Separation =	$\frac{1}{lines/metre}$
Fringe Spacing	w = $\frac{λD}{s}$
Incident light wavelength	nλ = d $\sin$ $\theta$
Standing Waves: String experiment Equation 1	Mass/unit length: $\mu$ = $\frac{M}{L}$
Equation 2	Tension: T = mg
Equation 3	Wavelength given as: $\lambda$ = 2l
Equation 4	Frequency: f = $\frac{1}{2l}$ $\sqrt {\frac{T}{μ}}$
Equation 5	v = $\sqrt {\frac{T}{μ}}$
