Here's his solution:

Homework Statement My car has rear defrosters that are made of 13 wires embedded into the rear window. They can melt a thin layer of ice, roughly 2.25*10^-2 kg worth, in two minutes. These wires are all in parallel and are connected to the 12V battery of my car. Each is about 1.25m long and...

Must the intermediate image be formed at the focal point of the eyepiece? I think that could solve my distance dilemma.

Homework Statement The barrel of a compound microscope is 15 cm in length (distance between lenses). The specimen will be mounted 1.0 cm from the objective, and the eyepiece has a 5.0-cm focal length. Determine the focal length of the objective lens. Known: f2=5cm, L=15cm, do1=1cm...

Ohhhh.. okay. I don't know how I didn't see that. Becuase h is Planck's constant, difference in energy is proportional to frequency.. so it would be a lower frequency photon.. like red or orange.. Got it.. =) Thanks

Ohh okay. So the CHANGE in energy between the excited state and intermediate state is smaller than the change in energy between the excited state and the ground state. So the equation: Change in energy = h * f provides: A smaller change in energy creates a higher frequency photon. Violet...

Hello. I'm trying to grasp this concept. The question states: An excited atom decays to its ground state and emits a photon of green light. If instead the atom decays to an intermediate state, what color of light might be emitted? I have the electromagnetic spectrum with the visible lights...

Ahh.. de Broglie's.. wavelength = h / momentum.. Because h is Planck's constant.. and momentum is constant in this example. wavelength is constant.. So they both have the same wavelength. Thanks.

Hi. There's this question that was posed. And I'm totally lost.:redface: If my professor explained how it's all derived it would've been useful. Here we are: A bullet and a proton have the same momentum. Which has the longer wavelength? Any help? Thanks, Cataklyzm
