Ghost images are formed in a TV picture when the electromagnetic wave from the broadcasting antenna reflects from a building or other large object and arrives at the TV set shortly after the wave coming directly form the broadcasting antenna. If the reflected wave arrives 5.0x10-7s after the direct wave, what is the difference in the distances traveled by the two waves?

"(a) 0.6 x10^15m(b) 1.67x10^-15m(c) 0.06x10^-1m(d) 150m(e) 300m"

"At a certain point and a certain time the electricfield of an electromagnetic wave is in the negativezdirection and the magneticfield is in the positiveydirection. Which of the following statements is true?"

"A. Energy is being transported in the positivexdirection but half a cycle later, when theelectricfield is in the opposite direction, it will be transported in the negativexdirectionB. Energy is being transported in the positivexdirection and half a cycle later, when theelectricfield is in the opposite direction, it will still be transported in the positivexdirectionC. Energy is being transported in the negativexdirection but half a cycle later, when theelectricfield is in the opposite direction, it will be transported in the positivexdirectionD. Energy is being transported in the negativexdirection and half a cycle later, when theelectric field is in the opposite direction, it will still be transported in the negative xdirectionE. None of the above are true"
