8 ) Investigate the nature of wave behavior to illustrate the concept of the superposition principle responsible for wave patterns, constructive and destructive interference, and standing waves (e.g., organ pipes, tuned exhaust systems).

a. Predict and explore how wave behavior is applied to scientific phenomena such as the Doppler effect and Sound Navigation and Ranging (SONAR).

The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense. In this episode of Crash Course Physics, Dr. Shini shows us how we know that light exists as a wave and why that's really cool.

[SC2015] PHYS (9-12) 10 :

10 ) Plan and carry out investigations that evaluate the mathematical explanations of light as related to optical systems (e.g., reflection, refraction, diffraction, intensity, polarization, Snell's law, the inverse square law).

What is light? That is something that has plagued scientists for centuries. It behaves like a wave and a particle. Is it both? In this episode of Crash Course Physics, Dr. Shini introduces the idea of quantum mechanics and how it helps us understand light. Also, there's this thing called the ultraviolet catastrophe.

Why is e=mc2 a big deal? What about probability? In this episode of Crash Course Physics, Dr. Shini attempts to explain a little more on the topic of quantum mechanics. She explores wave-particle duality, probability density function, and the Heisenberg Uncertainty Principle.

The more we learn about waves, the more we learn about a lot of things in physics. Waves can help explain everything from earthquakes to music. This video explores waves and how they travel.

We learn a lot about our surroundings thanks to sound. In this episode of Crash Course Physics, Dr. Shini goes over some of the basics (and some of the not so basics) of the Physics of Sound.

Music plays a big part in many of our lives. Whether you just like to listen or you enjoy playing an instrument, music is powerful. So what is music? How does it work? This video explores how sound travels in waves.
