A laser emitting at 350 nm passes through a cuvette containing water. Due to the Raman effect, as the laser passes through water, it loses energy to excite vibrational modes of water molecules. Consider only the vibrational level in water corresponding to the stretching of the OH bond which occurs at about 3500 cm−1. What is the wavelength of the laser radiation after it went through the water if the energy is lost due to the excitation of one vibrational quantum? You must express the final results in terms of the wavelength of the laser radiation in nm

A thin beam of laser light of wavelength 514 nm passes through a diffraction grating having 3952 lines/cm. The resulting pattern is viewed on a distant curved screen that can show all bright fringes up to and including ?90.0? from the central spot. If the experiment were performed with all of the apparatus under water (which has an index of refraction of 1.33), what would be the TOTAL number of bright spots that would show up on the screen?
