Light of wavelength 600 nm falls on a 0.49 mm wide slit and forms a diffraction pattern on a screen 1.0 m away.
(a) Find the position of the first dark band on each side of the central maximum.
mm
(b) Find the width of the central maximum.
Assume a rocketship in deep space moves with constant acceleration equal to 9.8 m/s2, which gives the illusion of normal gravity during the flight. Estimate the time required by a rocketship to attain the speed of light and the distance travelled t..
A single loop of wire with an area of 0.0900 m2 is in a uniform magnetic field that has an initial value of 3.80 T, is vertical to the plane of the loop, and is decreasing at a constant rate of 0.190 T/s.
Three charges are located along the x-axis. Charge A (+5.00x10-6 C) is located at the origin. Find the total force (and direction) on charge B
A steel wire is used to stretch a spring. An oscillating magnetic field drives the steel wire back and forth. what stretch of the spring produces a standing wave with six nodes
