Examples: Question 1: A sound has a frequency of 440 Hz what is its wavelength? Answer: Wavelength = Velocity (340 meteres per second) divided by Frequency (440 Hz) which is 0.77 metres Question 2: A soundwave has a wavelength of 5 metres, what is its frequency? Answer: Frequency = Velocity (340 m/s) divided by Wavelength (5 metres) which is 68 Hz 5. PHASE So far we have been looking at single sounds in isolation, but in the real world obviously, you can have several sounds occurring at the same time. Phase deals with how 2 or more sounds interact together either constructively or destructively. Please view the video below to get an idea what phase is. |
