Physics SL/HL Topic 4: Waves (videos are all on youtube)

[MitchCampbell]

I've just finished a set of 33 new videos that cover the entirety of the IB Physics SL and HL Topic 4: Waves

Here is an outline of the videos (ones with stars are extras that aren't needed in the syllabus, but I thought were fun to add anyway)

Topic 4: Waves

1. Waves intro (transverse and longitudinal waves, explosions in space)
   
2. Wave characteristics (wavefronts, rays, period, amplitude, wavelength)
   
3. Wave equation (wave equation, thunder and lightning, buoy in water)
   
4. **How a speaker works
   
5. Electromagnetic spectrum (visible light, infrared, radio, ultraviolet, x rays, gamma rays - examples of each)
   
6. **Breaking the sound barrier (supersonic, mach number, mach angle, planes, cars, bullets, freefall)
   
7. Reflection of waves (flat surface, string with open or closed end)
   
8. Refraction of waves (Snell's law, example)
   
9. Applications for refraction (distorted images, dispersion, rainbows, prisms, mirages)
   
10. Diffraction (diffraction conditions, large aperture, small aperture, examples)
    
11. Interference (constructive and destructive interference, path difference, examples)
    
12. Superposition of waves
    
13. **How noise canceling headphones work
    
14. Intro to Simple Harmonic Motion - SHM (definition, examples)
    
15. The key SHM equation (the one equation and its graph that helps with everything)
    
16. Kinematics of SHM (equations for position, velocity, acceleration)
    
17. Energy in SHM (potential and kinetic energy, conservation of total energy, pendulum cat)
    
18. Damping (underdamped, critically damped, overdamped)
    
19. Resonance (natural frequency, forced oscillations, resonance, examples)
    

Here is the playlist on youtube:

I hope this can help you. More videos on the way!

Cheers for the great work!

This is great! If only I had been able to use it last year.. >_> but for anyone who's in yr 1, or going into it, this is a great resource.
