Test #2 Review - Chapter 7 Flashcards
Visible light given off as a result of high temperature.
Incandescent
Change in a direction of a light ray.
Refraction
The law of reflection states that the angle of reflection is equal to
The angle of incidence
When something gives off light it is said to be…
Luminous
A type of mirror which gathers and focuses light.
Concave
The angle between the normal and reflecting surface.
90°
Material which allows for the transmission of light.
Transparent
A type of mirror that spreads light out.
Convex
The color of the visible spectrum with the longest wavelength.
Red
Materials that do not allow for the transmission of light.
Opaque
The particle associated with light energy.
Photon
The type of electromagnetic radiation with the highest frequency.
Gamma Rays
Speed of light in a vacuum
3.0 x 108 m/s
When a light ray moves from one material to another with a slower speed of light, the ray is refracted…
Towards the normal
The type of electromagnetic radiation released when heat is given off.
Infrared
The order of colors of visible light from low to high energy.
Red, Orange, Yellow, Green, Blue, Indigo, and Violet
Type of electromagnetic radiation with higher energy than X Rays
Gamma Rays
Type of electromagnetic radiation with a longer wavelength than infrared radiation.
AM/FM Radio waves TV waves, or microwaves
Portion of the electromagnetic spectrum that can be seen by the human eye.
Visible light
