So then the desired equation is 2ndcosθ=(m-.5)λ? How would I figure out the angle? I thought it was the right equation. Here is my instructors answer: If the thickness of the film is t, the difference in phase between a ray reflecting off the top surface of the film and one reflecting off the...

When working problems using Rayleigh's Criteria: θmin=1.22 [λ/D] Why do the answers come out in radians? I'm sure it has something to do with the aperture being circular but I don't understand why. Thanks!

Homework Statement When a thin soap film is very thin, we see it as black. How thick (in nm) is the film in the region where we see the first red band? Take the wavelength of red light to be 752 nm and the index of refraction of the soap to be n = 1.33. Homework Equations [2nt/λ] - 1/2...

Homework Statement Blue light of wavelength 400 nm passes through two slits which are a distance d = 1×10−4 m apart. This produces a double slit pattern on a screen L = 12 m away. (The screen is parallel to the plane of the two slits.) If the central bright fringe is denoted the “m=0...

Hey no problem, thanks a bunch!

Yes great, I knew that already. Can you be a little more helpful and explain why? Statements of fact are of little help.

I was trying to copy and paste it straight from the web site, which I learned only works for the text. I ended up saving it on my desktop and then uploading it to my question as an attachment. Thanks!

I have added an attachment of the circuit for clarity. I initially began by assuming that the 13 ohm and 24 ohm resistors were in parallel and I got the Req for them. Then since the top resistor seemed to be in series with them I added its value. This is wrong of course, the correct sequence...

Good morning! I want to ask a detailed circuit question and while I could coherently describe it, it would be much easier to be able to just copy the illustration of the circuit. The circuit doesn't copy into Physics Forums though. Any suggestions or does Physics Forums have some sort of...

Two 0.525 m rods, one lead and the other copper, are connected between metal plates held at 2.00°C and 106°C. The rods have a square cross section of 1.50 cm on a side. How much heat flows through the two rods in 1.0 s? Assume no heat is exchanged between the rods and the surroundings...
