Resolving Power of a Telescope | Physics with Professor Matt Anderson | M28-14

If I look up into the night sky, I can see individual stars. But what if one of those stars was really TWO stars, a binary system. How could I tell? Well, if I used my telescope I might be able to tell, but how big a telescope would I need? Let's find out.

Love these kinds of problems. There's a version of this where you can find out how far the spots are separated on the screen, or film (etc). The equation you used is in my first physics book (Giancoli). I almost remember the page number it's on, but I remember it's on an even page number, and I remember having a couple homework questions with it. Way kewl.

Physics is interesting if taught well...
Always good to catch your lectures...

I don't understand why we don't just say theta is equal to arctan(h/L) here? The value given without the approximation is an order of magnitude smaller.

Hey althogh i dont geek out on math watchin you explain the mental gymnastics of everything math excluding my opinion is cool 🤔🤙🏻🇺🇸
