is there a chance that for each topic, you'll run through definitions and stuff and common questions we might encounter for each topic? love your videos, you are a godsend x
Well, that's kind of the purpose of the videos themselves. Each video comes from my own opinion on each of the most important subtopics from every topic. As for common questions, those you can practice with past exams. If your school gets you access to the ManageBac Passport, OSC Study has a bunch of past exams where we have video solutions walking you through every step of the way! :) Cheers, Mitch
Hey Mitch, for the example you gave, I think you might have done a calculation error. I got the value of theta as being 2.54*10^-6. Please could you confirm if I got the right answer, or if I am doing something wrong here? Thanks in advance
I just did the calculation again to double check. 1.22 X 550 * 10^-9 / 2.4 = 2.79 x 10 ^-7. I'm not sure what your error was - try doing the calculation again just to be sure.
To record the videos, I use Camtasia to record what I'm doing on the screen. I'm using a writing program called Baiboard, but there are lots of other ones as well that are great.
Nice work! That's a pretty crazy satellite. Good news though, if you change the wavelength of the light, it can make a difference for your resolution as well.
