I tried to set up these experiments of diffraction or interference and then show them in the lab by using some cameras. So it was appreciated rather than just writing down, I don't use any power points or still do work out all the math in the class.

It depends if the basic experiment is like I do it myself. Sometimes they're already, for example, each student will build his own experimental set up. If I have to show their set up, of course, I take their help and say that, okay, it's built
