- 1. BANYAN TREE SCHOOL JAGDISHPURAMETHI SEMINAR TOPIC WAVES SUBMITTED TO MR. MANOJ SRIVASTVA (HOD,PHYSICS DEPARTMENT) UNDER THE SUPERVISION OF MR. ALOK MISHRA SUBMITTED BY ISHA MAURYA

- 3. What is awave? WAVE - a vibration or disturbance in space.
- 4. What is awave? Waves transfer energy without transferring matter.
- 5. How are wavesclassified? Waves are classified by WHAT they move through or by HOW particles move through them.
- 6. What material dowaves move through? MEDIUM- the substance that waves travel through and need to have in order to move. AD_The%2520Horizon%2520became%2520a%2520Thousand%2520Waves%2520-%25201
- 7. Classification of Waves Accordingto what they move through (Medium) Electromagnetic waves Mechanical Waves
- 8. Electromagnetic Waves Waves thatcan travel through matter or empty space where matter is not present.
- 9. Types of Electromagnetic Waves radiowaves microwaves infrared waves visible light ultraviolet rays X-rays
- 10. Mechanical Waves Needs amedium require the particles of the medium to vibrate in order for energy to be transferred.
- 11. Types of Mechanical Waves waterwaves earthquake/seismic waves sound waves waves that travel down a rope or spring
- 12. Classification of Waves Accordingto how particles move through them Transverse waves Longitudinal Waves
- 13. Transverse Waves Particles move perpendicularto the motion of the wave
- 14.
- 15. Wavelength (λ) The distancefrom crest to crest (or trough to trough); expressed in meters
- 16. Amplitude (A) The distanceof crest (or trough) from the midpoint of the wave
- 17. Longitudinal Waves particles move parallelto the motion of the wave.
- 18. Longitudinal Waves Compression- acrowded area causing a high- pressure region Rarefaction- a spread out area causing a low- pressure region
