Question
The plot below shows the index of refraction for fused quartz as a function of wavelength (where
the wavelength is the wavelength in vacuum).
1.48
Index of refraction
1.47
1.46
a
1.45
300
400
500 600
Wavelength (nm)
700
800
Assuming the index of refraction is approximately given by the equation
a
n = 1+
wo - w²
Nq²
2€0m
what is the resonant frequency (w0) of the fused quartz? (Brute force Hint: you could read off
two points from the curve, solve for w0 and then check your answer with a third point on the
curve). Don't forget that that w=2nf, and f^x=c, and l= wavelength.
Its okay when you pick the third point on the curve you don't get the same w0.
