BAP 100 – EXERCISE 1 – BARRY MOORE 1.wavelength = velocity / frequency wavelength = 344 / 2135 wavelength = 16cm 2.frequency = velocity / wavelength frequency = 344 / 32 frequency = 1075Hz 3.Phase is when two wavforms interact with eachother. If two waveforms interact with eachother out of phase meaning they are out of time (not synchronised) they will cancel eachother out meaning there will be a moment of silence wherever they interact. this can cause issues in recording and mixing because unexpected silence is not desirable for the artist or the listeners. If two of the same waveforms meet in phase (synchronised), the new waveform will be exactly the same in frequency, shape and phase however it will have doubled in amplitude. This can cause the track not to have…show more content…
6.the seven fundamental characteristics of any waveform are: wavelength – is the distance covered by a waveform from the start to finish of a cycle. wavelength is represented by the lambda (λ) symbol and measured in Hertz(Hz). the formula needed to calculate the wavelength of a waveform is: λ = v/f which is wavelength = velocity divided by frequency. phase – is the interaction of two or more waveforms. waveforms can interact in and out of phase. if two waveforms meet out of phase they will cancel eachother out and there will be silence. if they meet in phase the new waveform will be exactly the same in shape and frequency but it will have doubled in amplitude velocity – is the speed at which the sound wave is propelled through a medium. at a temperature of 20 degrees centigrade, sound travels at 344 meters per second. the velocity of sound is dependant on the temperature of the medium it is travelling
