1. The problem statement, all variables and given/known data A tuning fork with a frequency of 420 Hz emits sound with a wavelength of 0.82 m in air. If the temperature of the air increases, what will happen to the wavelength and why? 2. Relevant equations 3. The attempt at a solution I know temperature affects speed but I am not so sure how it affects wavelength. Maybe: When the temperature increases the speed will increase, therefore the wavelength will increase because the particles are spread apart? ( Just a thought) Please explain, any help appreciated!
