Presentation Transcript

  1. WAVES • KEY TOPICS DEFINITION OF WAVES WAVE PARAMETERS – f, T, A, l PHYSICAL PROPERTIES WAVE SPEED WAVE TYPES SUPERPOSITION & STANDING WAVES DOPPLER EFFECT & BOW WAVES

  2. WAVES • DEMO

  3. WAVE • THE FOLLOWING DEMO SHOWS THAT A WAVE ON A SLINKY CARRIES ENERGY. • DEMO

  4. WAVE PARAMETERS • AMPLITUDE • WAVELENGTH • FREQUENCY or PERIOD

  5. DEMONSTRATION • WAVE PARAMETERS CAN BE DEMONSTRATED WITH A ROPE

  6. FREQUENCY • THE RATE OF VIBRATION OF THE MEDIUM OR SOURCE • SYMBOL - f • UNIT - Hz

  7. PERIOD • THE TIME FOR ONE COMPLETE VIBRATION OF THE MEDIUM (OR THE SOURCE) • T = 1 / f

  8. PHYSICAL PROPERTIES OF WAVES WHEN A WAVE ENCOUNTERS AN BOUNDARY BETWEEN TWO MEDIA THE ENERGY CAN BE: REFLECTED TRANSMITTED ABSORBED

  9. WAVELENGTH & FREQUENCY THE FREQUENCY AND WAVELENGTH ARE INVERSELYPROPORTIONAL DEMO

  10. SPEED OF A WAVE • THE FOLLOWING DEMO SHOWS HOW TO CALCULATE THE SPEED OF A WAVE • DEMO

  11. DEMO DEMO

  12. WATER WAVES • WAVES ON THE SURFACE OF WATER ARE A COMBINATION OF TRANSVERSE AND LONGITUDINAL • DEMO

  13. ACTIVITY USE A SLINKY TO DEMONSTRATE: WAVES TRANSMIT ENERGY FREQUENCY & PERIOD AMPLITUDE WAVELENGTH WAVES CAN BE REFLECTED WAVES CAN BE TRANSMITTED WAVES CAN BE ABSORBED THE SPEED CHANGES IF THE MEDIUM CHANGES TRANSVERSE AND LONGITUDINAL WAVES
