1. Relating Frequency and Wavelength of Electromagentic Radiation. Most of the light from a sodium
vapor lamp has a wavelength of 589nm. What is the frequency of this radiation?
We can first convert the wavelength of the light
1) You have a leak-proof piston filled with a gas. If the initial pressure is 1.50 atm
and the initial volume is 3.0 L, what is the volume if the pressure is increased to
4.50 atm?
P1V1=P2V2
1.50atm x 3.0L = 4.50atm x V2
V2 = 1.0 L
