While watching a recent science fiction movie, one klingon spaceship blows up a droid spaceship with a laser gun. the klingon crew watches out the port window and covers their ears to muffle the noise from the explosion. scientifically, this scene is inaccurate because a) light can not reflect off objects in the vacuum of space. b) they would not be able to see anything outside the window. eliminate c) lasers can not be transmitted through the vacuum of space. d) the sound of the explosion would not be transmitted back to their ship.

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass
