Light in a transparent material that has an index of refraction of 1.333 strikes the boundary with another transparent material for which the index of refraction is 1.010.

What is the critical angle for total internal reflection between these two materials?

Question 2

A balloon originally has a volume of 1.0 m3 when the gas in it is at 20C and under a pressure of 1.0 atm. As it rises in the earth's atmosphere, its volume expands.

What will be its new volume if its final temperature and pressure are -40C and 0.10 atm?
A) 8.0 m3 B) 6.0 m3 C) 4.0 m3 D) 2.0 m3
