- 1 points SERCP11 24.2.OP.004. My Notes || Ask Your Teacher A laser beam is shined upon a dark shield with two narrow slits. As a result, an interference pattern forms in the space on the other side of the partition. The wavelength is 630 nm, and the first-order bright fringe lies at a 14.8° angle from the central maximum. What is the slit separation (in pm)? um Need Help? Road

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A student stretches a spring, attaches a 1.90 kg mass to it, and releases the mass from rest on a frictionless surface. The resulting oscillation has a period of 0.650 s and an amplitude of 30.0 cm. Determine the oscillation frequency, the spring constant, and the speed of the mass when it is halfway to the equilibrium position. HINT (a) the oscillation frequency (in Hz)...
