- The Spectrum
- What are the wavelengths of visible light?
- How do we describe light with wavelengths shorter (or longer)
than visible light?
- What is the color ordering in the visible spectrum?
- Dispersion
- What is the relation between the index of refraction and the
speed
of light?
- Blue light has a higher frequency than red light. Since it
oscillates
faster, it is more likely to scatter than red light.
- Since blue light scatters more than red light, it moves slower
in
dense materials like glass.
- Why does blue light bend more than red light in glass?
- When white light enters a prism, how does it exit as different
colors?
- Can you draw a similar picture for how light breaks up into a
rainbow when passing through a water droplet?
- What causes a `double' rainbow?
- Scattering
- What is meant by Rayleigh scattering?
- How does the scattering of light depend on the frequency?
- Why is the sky blue?
- Interference
- What is the interference pattern seen from light passing through a
double-slit?
- A thin film will reflect from both the top and the bottom
surface, which creates a color interference.
