PPT-Vibrations & Waves Vibrations and Waves

Periodic Motion Motion that repeats in a regular cycle is called periodic motion The revolution of a planet about its sun is an example of periodic motion The highly reproducible period T of a planet is also called its year.

Your ear converts sound waves into nerve impulses that your brain interprets.. The ear’s structure is designed to receive and transmit the sound waves.. Doppler Effect. ~apparent change in frequency of a wave due to the motion of the source of the wave.. If the object is moving towards the observer the frequency will appear to increase. If the object is moving away from the observer the frequency will appear to decrease. Waves-3. resonance . clocks – pendulum . springs . harmonic motion . mechanical waves . sound waves .
