g Light is sent between two finite slits. We changed something about the system (wavelength, slit width, slit separation, or number of slits) to get from the upper interference pattern to the lower pattern. show answer No Attempt 33% Part (a) What change was made in going from the top picture to the bottom one

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
