1. The problem statement, all variables and given/known data what happens to wavelength if temperature increases? 2. Relevant equations V= lambda * frequency 3. The attempt at a solution I'm guessing since no change to frequency is stated?.. and I know that the speed of sound increases as temperature increase. The wavelength would have to increase in order to balance the equation V= lambda * frequency? But I'm not sure if it's correct or why and if frequency would be affected by temperature or not.. I can't find a straight answer or explanation on google so here I am.
