When a stretched string is vibrated up and down with a particular frequency, it causes a standing wave to be produced. An experiment is performed in which several different frequencies are used to produce corresponding standing waves with specific wavelengths.

The frequency is the variable and the wavelength is the variable.

The independent variable is usually placed on the axis and the dependent variable is placed on the axis.

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
