1.Does doubling the frequency of a wave source doubling the speed of wave?
2.Do most people can detect frequencies as high as 20 000 Hz?
3. Does the wavelength of a wave is then determined by the frequency and speed?
4.Does sound travels faster than light?
5.Is frequency dependent with the wavelength?
(Just Answer yes or no)
