Optics
Review wave basics by analyzing phenomena in which light behaves as a wave.
Learn why the sky is blue, sunsets are red, and how rainbows form.
Become familiar with the vocabulary of reflection and refraction:
incident ray, angle of incidence, reflected and refracted rays, angle of refraction, normal.
Explain how plane, convex, and concave mirrors form images.
Explain how convex and concave lenses form images.
Learn how to use ray diagrams to determine optical effects:
principal axis, center and radius of curvature, image and object distance, focal point and focal length.
Be able to describe images as enlarged or reduced, upright or inverted, real or virtual.
Apply Snell's law to refraction at boundaries, including critical angle and total internal reflection.
Q: Where do bad rainbows go?
A: Prism, but its a light sentence, and it gives them time to reflect
I don't think he needed the corny sign. It was already disturbing enough. WHY does light slow down in water (or glass).
PhET interactive sim for learning about reflection and refraction of light.
Please explore these oPhysics simulations on Light.
A neat video about the public images released from Hubble and James Webb space telescopes explains the spikes seen on images of stars.
