For the following homework problems please show all of your work.
1. If the energy of a photon is given by the equation E = hv, where
h is known as Planck's constant, and has the value of h = 4.136 x
10-15 eV -s, then complete the following table. Please note: the unit
called an electron volt (eV) is a unit of energy whose value is compa-
rable to the values seen in atomic transitions, and a Hertz is Hz = 1/s.

The second brightest star in the sky (after Sirius) is Canopus. This yellow-white supergiant is about
1.13616 x 1016 kilometers away. How far away is it in light years?
28.1
8* Regulus (one of the stars in the constellation Leo the Lion) is about 350 times brighter than the sun. It is 85
light years away from the earth. How far is this in kilometers?
9. The distance from earth to Pluto is about 28.61 AU from the earth. Remember that an AU = 1.496 x 108 km.
How many kilometers is it from Pluto to the earth?
10. If you were to travel in a straight line from Los Angeles to New York City, you would travel 3,940
kilometers. How far is this in AU's?
11. Challenge: How many AU's are equivalent to one light year?

Which color would deliver more photons each second? All the photoelectrons that are produced from the light are presumed to be collected by another electrode and we determine the current in amperes using a circuit and an "ammeter", that is, some device that can give a precise quantitative measure of the current. Such a device might use the magnetic field generated by the current, or the voltage produced when the current flows across a resistance. 2.
