PLS HELP!! A student uses a 320 Hz tuning fork during a lab Investigation into the speed of sound. If air temperature in the classroom is 20 degrees Celsius, what is the wavelength of the sound waves produced by the tuning fork?

From the graph the speed of the snail in the first 20 seconds centimeter/second. after that, the snail remains in the same place for seconds

Which statement correctly describes the relationship between frequency and wavelength?
