Your 1.1 cubic foot GE microwave oven generates 1100 watts of microwaves at a frequency of 2.45 GHz.
a. What is the wavelength of the microwave radiation being emitted?
b. How many photons per second of microwaves are being emitted?

A proton beam is made by accelerating protons in a high voltage electric field. The protons have a velocity of 2.75 x 107 m/s. What is the wavelength of the protons traveling at this very high speed?

For the proton question, see here:

Look at problem #2 (a bit less than half-way into the file)

For the microwave questions:

Convert 2.45 GHz = 2.45 x 10^9 s^-1 and then use it in λν = c to solve for the wavelength:

(λ) (2.45 x 10^9 s^-1) = 3.0 x 10^8 m/s

This gives you the wavelength in meters.

Example #14 has watts in it. Look at steps 2 and 3 in the solution to help you with part b. Remember, a watt is 1 J per second.
