Light waves, for which the electric field is given by ey(x, t)=emaxsin[(1.40×107m−1)x−ωt], pass through a slit and produce the first dark bands at ±28.6∘ from the center of the diffraction pattern.

part a

what is the frequency of this light?

part b

how wide is the slit?

express your answer with the appropriate units.

part c

at which positive angle will the next dark band occur?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
