Thank you, guys, for interesting discussion.

Hesch, can you share source code of your program?

Thanks for reply, it helped.

Homework Statement I found solution to problem 257 from "300 Creative Physics problems" hard to understand. In that problem we have very long solenoid with coil wounded in one layer. Data such as: density of turns, magnetic field at distance of 5 cm form the axis of solenoid and diameter (1 cm)...

Setup is similar to that: http://physics4cqtran.blogspot.com/2012/10/experiment-12-cd-diffraction.html, but instead laser I used remote control. IR is invisible, but some cameras (like mine) are able to see IR - in this setup I saw light from remote control, but diffraction spots didn't appear.

1. Homework Statement Hi, I have to do lab experiment - estimating infrared wavelength (from remote control). My experimental setup includes CD, remote control, webcam (without IR filter, so I can see the infrared radiation), sheet of paper (I will see diffracted light spots on it) with hole...
