the photobeam should be blocked at that point and the question also give a diagram and the bob does continue on after reaching the lowest point, so it doesn't just hang at rest

Thanks in advance for the help! I really appreciate it :D Homework Statement A pendulum was swung once and when the pendulum bob was at the lowest point of its swing, it broke a photogate light beam. The following information was collected: Diameter of pendulum bob = 3.50cm = 0.035m mass of...

Thanks in advance for your help! I'm currently doing this independent study and have nothing to help me with these questions except some lesson books that came with the course, but explains hardly anything and this site. 1) so, I have to design and complete an investigation to determine...

do i find the angle of refraction for red and violet in the crown glass with n1*sinθ1 = n2*sinθ2 also? here's my attempt..i think it's wrong though, because what I'm not sure w/ is what do i put for n2 in the equations... crown glass: n=1.52 ethanol: n=1.36 red: sinθ2=(n1*sinθ1)/n2...

Hi, I know I've seen this question on this site before, but it didn't explain how to do it. I don't even know where to begin... Q: Consider the optical interface between crown glass and ethanol. b) White light travels from crown glass into ethanol. If the angle of incidence in crown glass...
