You have a 1 W light bulb in your lab. It puts out light of only 1 frequency. The wavelength of this light is 500nm. you set up a detector with a surface area of 1 square cetimeter facing the light source at a distance of 100m.

1.) find the number of photons hitting the detector every second.

2.) what is the maximum E field of the E M wave hitting the detector? Answer in mN/C.

3.) what is the maximum value of the B field of this E M wave? Answer in pT.

4.) how far away would you have to place the detector to only receive 1 photon per second from the light bulb? answer in km

We did a lab studying resistance and Ohm’s Law. In my lab, my light bulb circuit element did not obey Ohm’s law b/c my data did not convey a proportional relationship between voltage drop and current. How do I answer: If either or both of your circuit elements did not obey Ohm’s Law, can you think of any reasons for the non-ohmic behavior? In other words what might be happening to one or both of the elements as the applied...
