Project in Physics: WAVES
- 1. waves the facts about themCuevas | Prado | Santos |}Bunayog(IV-Einstein)
- 2. ! Identifythedifferenttypesofwaves To differentiatepulse wavesand periodic waves To distinguish transverse and longitudinal waves To relatewavevelocity, wave length and frequency checklist (Objectives)
- 3. Minute to win it! (Challenge: Waving rope) You will need 9 foot rope 12cm (Diameter) ring A Partner
- 4. 1. The objective of the game is to transfer the ring from one end of the rope to the other end. 2. The player must transfer the ring by waving the rope in motion. 3. The player who completes the challenge within a minute wins the prize. You’ve got a minute to win it! You’ve got a minute to win it!
- 5. Let’s start the discussion WAVES: Natureofwaves Typesofwaves Parts of a wave Measuresofa wave
- 6. Before we start Before we start We would like to point out that we strongly disagree with this*and you should too.
- 7. Nature of waves Lesson #1:
- 8. Waves Topic: Nature of waves Topic: Nature of waves »A disturbancethat carriesenergythrough matteror space. They are seriesof pulsestravellingatregularintervals.
- 9. Medium Topic: Nature of waves Topic: Nature of waves »Matterthrough which a wavetravels. Pulse »Disturbancein a medium
- 10. Types of waves Lesson #2:
- 11. Mechanical waves Topic: Types of waves »Waves that require a medium Topic: Types of waves According to medium: Example: Sound waves, water waves Sound Water waves
- 12. Topic: Types of waves »Waves that donot require a medium Topic: Types of waves According to medium: Example: Light, radio, micro-waves Electro- magnetic waves LightRadio waves
- 13. Pulse waves Topic: Types of waves »Waves that consist of a single travelling pulse Topic: Types of waves According to Pulse: Periodic waves »Waves that continue to generate pulses
- 14. transverse waves Topic: Types of waves » Waves that move at a right angle or perpendicular to the direction of the wave, Topic: Types of waves According to movement:
- 15. longitudinal waves Topic: Types of waves » Waves that travel along the direction of the wave Topic: Types of waves According to movement:
- 16. Surface waves Topic: Types of waves » Combination of transverse and longitudinal waves Topic: Types of waves According to movement:
- 17. Parts of A wave Lesson #3:
- 18. Topic: parts of a wave Topic: parts of a wave Longitudinal wave:
- 19. Topic: parts of a wave Topic: parts of a wave Longitudinal wave: »Region wherethe points are pressed together »Region wherethe coils are spread out Compressio n Rarefaction
- 20. Topic: parts of a wave Topic: parts of a wave Transverse wave:
- 21. Crest Topic: parts of a wave Topic: parts of a wave Transverse wave: Trough »Points where the coils of the spring are highest »Points where the coils of the spring are lowest Amplitude »Maximum displacement of a particle on the mediumfrom its rest position; distance from rest to crest »Length of onecomplete wave cycle Wavelength
- 22. Measures of A wave Lesson #4:
- 23. Topic: Measures of a wave The velocity of the wave (v) is equal to the product of the wavelength (λ) and the frequency (f) Topic: Measures of a wave v = λf Where: v – velocity (m/s) λ – wavelength (m) f – frequency Equation:
- 24. Topic: Measures of a wave Sample Problem: If a dog whistle has a frequency of 30 000 Hz, what is the wavelength of the sound emitted? (approx. speed of sound = 340 m/s) Topic: Measures of a wave λ = v / f Given: v = 340m/s f = 30 000 Hz Equation: Asked:λ (Wavelength) λ = v / f = 340 m/s / 30,000 Hz = 0.011 m Solution: Answer:0.011 m
