For vibrational states, the boltzmann equation can be written as n1 n0 = e − δe kt, where n0 and n1 are the populations of the lower and higher energy states, respectively, δe is the energy difference between states, k is boltzman’s constant, and t is the temperature in kelvins. for temperatures of 15 °c and 50 °c, calculate the ratios of the intensities of the anti-stokes and stokes lines for ccl4 at (a) 218 cm-1 , (b) 459 cm-1 , and (c) 790 cm-1 . for each temperature and raman shift, calculate how much more intense the stokes line is compared to the anti-stokes line. room temperature is 298k

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

What is the speed of an object at a given moment?
