Study Notes
Characteristics of Light
- Light and all electromagnetic waves are transverse waves.
Visible Light
- The order of increasing frequency of visible light is: red, orange, yellow, green, blue, indigo, and violet.
Light and Surfaces
- When light is incident on dry surfaces, it reflects and/or absorbs.
- When light is incident on wet surfaces, it refracts and disperses.
Materials and Light
- Colored glass is translucent to much of incident white light.
- Opaque materials are opaque to much of incident white light.
Refraction of Light
- When light rays pass from air into water, they bend towards the normal.
- When light rays pass from water into air, they bend away from the normal.
Electrons and Light
- The frequencies of vibrating electrons are equal to the frequency of light.
Frequency Range of Light
- The frequency range for light waves is approximately 4.3 x 10^14 Hz to 7.5 x 10^14 Hz.
