Module 8: Week 8
- If the magnification produced by an optical system is negative, the image is
- Fresnel lenses are
- Choose the lens having the shortest focal length.
- A lens that is thinner at the center than the edges
- Diverging light rays from a nearby object (a few focal lengths away from the mirror) strike the surface of a concave mirror. After reflecting from the mirror’s surface, the rays will converge at
- In optics, what is meant by an “interface?”
- Image height divided by object height gives
- Liquid crystal displays make use of
- The Hubble Space Telescope
- Which angle is the angle of incidence for the light ray shown approaching the plane mirror?
- The light directly from the Sun is
- When light enters glass from air, which of these properties of the light change?
- You see colors in a rainbow because of
- According to the law of reflection, a light ray striking a mirror at an angle of incidence of 30 degrees will leaves the mirror at an angle of
- Two otherwise identical light waves arriving at the same point with peak matching valley undergo
- A diverging lens is thicker at the center than the edges.
- Your eye’s iris changes the size of your pupil to adjust the amount of light that enters your eye.
- A light ray can pass through a diverging lens without being deflected.
- You look at yourself in a plane mirror. If you move away from the mirror and look at yourself again, you now see more of yourself.
- A one-way mirror works because its surfaces are half-silvered.
- In order to see a rainbow, the Sun must be directly in front of you.
- The Hubble Space Telescope has been repaired.
- Liquid crystal displays make use of interference of light.
- Diverging lenses have negative focal lengths.
- Light goes slower through glass than through air.
- Select the closest matching pairs possible. Aberrations Refraction Law of Reflection Total Magnification internal reflection
