You're outside on a cold day (Tout = 0 °C) listening to your iPod with an external circular speaker having a diameter 0.0550 m. Because of the cold you decide to go inside where the temperature is 27.5 °C. If your favorite song begins with a 8.54-kHz tone, find the change in the diffraction angle of this tone assuming the air behaves as an ideal gas.

1). The change would be due to the expansion of the speaker, so we need to know what substances comprise the speaker. #2). A speaker with a diameter of 0.055m is not too good at reproducing 8.54 KHz. (3). I believe this is a bogus question.
