L
The angle of incident equals . . .
What is the angle of reflection?
The color that is known to absorb all other colors.
What is black?
The color that is known to reflect all other colors.
What is white?
A device that converts sunlight into energy.
What is a solar panel.
Measured in Hertz (Hz).
What is frequency?
The number of waves that pass a fixed point in one second.
What is frequency.
A straight line used to represent the path of a light wave.
What is a ray?
A form of radiant energy that travels in straight lines as waves and allows the human eye to see.
What is light energy?
Any object that produces its own light.
What is a light source?
A dark area created when an opaque object blocks light from passing through.
What is a shadow?
Materials that allow some light to pass through but scatter it, causing images to look blurry.
What is translucent?
What is amplitude?
Materials that block all light from passing through, they either absorb or reflect the light.
What is opaque?
The passing of light energy through matter.
Travels at the same speed - the speed of light.
What is an Electromagnetic Wave?
Materials that allow light to pass straight through clearly.
What is transparent?
The bending of light as it passes from one material to another, causing light to change speed.
What is refraction?
A disturbance that transfers energy through space and matter without needing a physical medium.
What is an electromagnetic wave?
The spreading out of light waves in all directions, which is what causes the sky to appear blue.
What is scattering?
The band of colors produced when white light passes through a prism.
What is the spectrum?
The bouncing back of light waves when they strike a smooth, shiny surface, like a mirror.
What is a reflection?
The process by which light energy is "soaked in" to matter and often converted into heat energy.
What is absorption?
A clear glass or plastic object used to separate white light into its component colors.
What is a prism?
The distance between one point on a wave and the identical point on the next wave.
What is wavelength.
The height of a wave from its resting position to the bottom of a trough.
What is amplitude?
