Light ray 1 strikes the smooth surface of a mirror as shown below. A horizontal line is labeled Mirror and there is one ray labeled 1 which falls on the mirror at a point and there are four rays of light labeled 2, 3, 4, and 5 which move away from same point on the mirror. Ray 2 is exactly vertical to the mirror, ray 1 is on the left of ray 2 and makes an angle of about 25 degrees with ray 2. Ray 3 is on the right of ray 2 and makes an angle of about 25 degrees with ray 2. Ray 4 is on the right of ray 3 and makes an angle of about 25 degrees with ray 3. Ray 5 is on the right of ray 4 and makes an angle of about 25 degrees with ray 4.

Which of the following is the reflected ray for ray 1?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
