Predict what happens to the wavelength of a wave on a string when the frequency is doubled. a)Assume that the tension in the string remains the same. Confirm your prediction mathematically.
b) The period of a sound wave from a piano is 1.20x10^–3 s. If the speed of the wave in the air is 3.40 x10^2 m/s, what is its wavelength?
c) A wave has a speed of 123 m/s and a frequency of 230 Hz. What is its wavelength?
