How to understand the reflection and refraction of light?
To understand the reflection and refraction of light you may:
Explain how light bends at the interface between two media and what determines the angle.
Apply Snell’s law to a laser beam incident on the interface between media.
Describe how the speed and wavelength of light changes in different media.
Describe the effect of changing wavelength on the angle of refraction.
Explain how a prism creates a rainbow.
