Questions: 1) An electron is shot at 106m/s between two parallel charged plates, as shown the following figure. If E between the plates is 1kN/C, where will the electron strike the upper plate? Assume vacuum conditions. Plate 0.5cm 10 m/s Plate

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
