2. The quartz tube is actually 921mm long × 15mm diameter ... use the tube circumference and length to:
a) calculate the light intensity , as it leaves the tube
b) estimate the light's maximum Electric Field , at the outside of the tube
c) and its max Magnetic Field there
d) use 1.
e) to calculate the Area density of photons leaving the tube , in 1 oscillation time.
3. The quartz tube is 1.00mm thick, and has a refractive index 1.61 at 253.7nm (thin quartz is transparent to 180nm)
a) compute the light's wavelength, speed, and frequency , as it passes through the quartz tube.
b) how many wavelengths "fit" within the tube wall thickness , on their way straight out?
c) if a photon had been going 13° from "straight out", before it hit the quartz, what angle does its path take within the quartz?
d) what is the biggest angle within the quartz (from straight out) that can actually escape the quartz?
