- A man lost in a maze makes three consecutive dis- placements so that at the end of the walk he is back
where he started, as shown below. The first displace-
ment is 8.00 m westward, and the second is 13.0 m
northward. Use the graphical method to find the
third displacement.

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
