The Doppler Effect and Sound Interference
The Doppler Effect- The Doppler effect is described as the effect produced by a moving source of waves in which there is an apparent higher shift in frequency for observers towards whom the source is approaching and an apparent lower shift in frequency for observers from whom the source is receding.
Doppler effect equation:
f'=v+vo/v-vs (f) <--- This equation refers to movement that brings two objects nearer to each other.
f'=v-vo/v+vs (f) <--- This equation refers to movement that brings two objects farther from each other.
Sound Interference- Sound interference is made up of numerous interferences.
Constructive interference- Constructive interference is if the amplitudes of two waves have the same sign, they will add together to form a wave with a larger amplitude.
Destructive interference- Destructive interference is If the two amplitudes have opposite signs, they will subtract to form a combined wave with a lower amplitude.
Constructive and Destructive numbers:
Constructive numbers will always be a whole number or something close to a whole number CI: !,2,3,4......16
Destructive numbers will always be an integer of .5 DI: .5,1.5,2.5,3.5,4.5..... .15.5
If the number is but near neither it will be heard as a normal sound.
