Question 6 of 6
6. Question
A student conducts an experiment to study the relationship between the frequency f, the
wavelength, l and the speed, v of the wave. The ripple tank has uniform depth of water. He
repeats the experiment with difference frequency, f and records the corresponding
wavelength, l and speed, v. Which graph below shows the variation of the wavelength l with
frequency, f?CorrectIncorrect
