At a temperature of 10°c the percent relative humidity is r10, and at 40°c it is r40. at each of these temperatures the partial pressure of water vapor in the air is the same. using the vapor pressure curve for water that accompanies this problem, determine the ratio r10/r40 of the two humidity values.

Write maxwell's equations and discuss the terms involved and the results of each equation in classical electrodynamics. if it is possible to write these equations in integral form, give the integral forms. find the wave equation for electromagnetic waves from the maxwell equations. what is the propagation velocity of electromagnetic waves in space according to the wave equation you find?
