I have a bunch of compasses. I guess I'll end up using them. I like qualitative labs, but these students are very bright and I like challenging them a little bit. However, I'm always short on supplies.
Thank you for that link! I'll read through it and see if I can take anything from it.
I found a box of air core solenoids and was hoping someone could me think of a useful lab to use them for. They are about 700 turns each. They carry 7 to 10 amps. However I think I think I would only be able to provide 3 amps because of the power supplies I have. I would like to use them to do...
The set up
The lettering on "Pale Ale" is white outlined in black.

That doesn't explain anything to me lol. I've tried this with different cans since I first saw this a few weeks ago. And sometimes white letters make white reflections but other times white letters make black reflections.
When looking at a diffraction pattern made by two slits, and trying to calculate wavelength, what do we count as fringes? For example, in this picture are there five total fringes or, like, 25?
I've been trying to set up a lab for my high school physics 2 class and the math says that every...
I've trying to explain this to myself but I know I'm missing something.
I tuned the low E string to B. The frequency of that note is about 62 Hz. When I play that note under the led lights in my backyard I can see the string oscillate back and forth.
After doing some reading, the LED light...
