When using 690 nm light to perform the double slit experiment, the interference in the middle is a bright fringe (constructive interference).
1. If the slits are 2.48 µm apart, at what angle will we observe the first-order dark fringe?
2. If we were able to observe the second-order bright fringe, at what angle would we expect it to be observed?
You can think of the work?kinetic energy theorem as a second theory of motion, parallel to Newton's laws in describing how outside influences affect the motion of an object. Use the work-kinetic energy theorem to find the net work that is done on t..
Physics: Simple Harmonic Oscillator, Traveling waves are set up in a pair of long strings by a simple harmonic oscillator. The strings have identical mass densities of 5.1 grams/meter.
A tank is in the shape of an inverted cone, having height h = 2.50 m and base radius r = 0.750 m. If water is poured into the tank at a rate of 15 L/s, how long would it take to fill the tank.
