You're doing a double-slit experiment with two different colors. You notice that the fourth-order bright fringe using 615nm orange light is in the same place as the fifth-order bright fringe of the other color.
What's the wavelength of that color?
At what temperature is the diameter of the hole equal.
A fireman 52 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of 32° above the horizontal.
A meterstick is at rest in an inertial frame S2. If S2 moves with a speed of 0.7c with respect to a rest frame S1, find the length of the meterstick as measured in frame S1 according to classical physics. Reply in units of m.
