Properties of Waves. Reflection, Refraction, diffraction. waves chapter 10 #foryou #physicsclass

*1. Reflection*

- Occurs when a wave hits a barrier and bounces back.
- Law of Reflection: Angle of incidence = Angle of reflection.
- Examples:
- Mirror reflection (light)
- Echoes (sound)
- Reflection off water surface (water waves)

*2. Refraction*

- Occurs when a wave passes from one medium to another with a different speed.
- Bent or changed direction due to change in speed.
- Examples:
- Bending of light through glass or water
- Change in direction of sound through air to water
- Refraction of seismic waves through Earth's layers

*3. Diffraction*

- Occurs when a wave encounters an obstacle or edge.
- Wave bends around the obstacle or spreads out.
- Examples:
- Bending of light around corners
- Diffraction of sound around buildings
- Water waves around rocks or pillars

These behaviors are crucial in understanding various phenomena in physics, optics, acoustics, and more!

Would you like me to elaborate on any of these?
