E3r light from a white source passes through a
filter that transmits only the band of wave-
lengths from 400 nm to 600 nm. when this
filtered light is incident normally on a certain
diffraction grating, the 400 nm light in one
order of the spectrum is diffracted at the same
angle, 30, as the 600 nm light in the adjacent
order. find the spacing between the lines in
the grating.

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.)
