When illuminated with light of wavelength 672 nm (6.72 x 10-7 m), the first dark fringe produced by a single slit lies a distance of 1.4 cm from the center of the screen placed 1.7 m from the slit. (a) how wide is the slit?

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
