What do sound waves and infrared waves have in common, and what makes them different? both carry energy through space, but sound waves are mechanical and infrared waves are electromagnetic. both can transfer energy through matter, but sound waves travel through air and infrared waves travel through space. both can transfer energy through matter, but sound waves can be heard and infrared waves can be seen. both carry energy through space, but sound waves require matter to pass through and infrared waves do not.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
