**1. Homework Statement**

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. Homework 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!
