A laser with wavelength λ is used for optical
communication from a tower on land to a ship located a distance
daway. The tower has a height of habove the water
and the receiving antenna on the ship is at the same height.
Unfortunately, the beam from the laser diverges so much that there
is a reflection of the laser off the water as well as the direct
radiation from the tower. When the two beams reach the ship they...

Red laser light of wavelength 650 ?? shines on a CD, which has tiny notches for each byte of information stored on the CD. You see that the distance between the 0th order bright spot and the 1st order bright spot is 26 ?? projected on the wall that is 60 ?? away from the CD. Determine the spacing between the notches on a CD. Determine the notches per millimeter on a CD. You repeat the experiment with a DVD,...
