Part B Light can bounce off objects. This is called reflection, and it’s what allows us to see objects. This drawing shows a light ray reflecting from the red construction paper. Although many light waves are hitting the paper and reflecting from it, showing just one ray helps us follow the path of a single wave.

a white ray of light hitting red construction paper and a red ray of light reflecting from the paper

For each color of paper, which part of white light is reflected?

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?
