4) A ray of light travels in the xy plane. I starts with a velocity with +x and +y components, traveling at an angle 10 deg above the x axis. It bounces off a vertical mirror that has its normal vector point in the x direction. It then bounces off a mirror that has a normal vector with +x and -y components, pointing 40 degrees below the x axis. What direction will the light be traveling after bouncing off the two mirrors?
please show work, thanks
