Basics of Light
A form of electromagnetic radiation that is visible to the human eye.
What is light?
The bouncing back of light when it hits a surface.
What is reflection?
Any device that manipulates light, such as lenses, mirrors, or prisms.
What is an optical device?
What is the primary colors of light?
What isred, green, and blue?
Objects that allow light to pass through them.
What is transparent?
How does light travel
What is in a straight line?
The bending of light as it passes from one medium to another
What is refraction?
Thicker in the middle and thinner at the edges, causing light rays to converge after passing through it.
What is convex lens?
How does an object appear when it reflects all colors of light?
What is white?
Objects partially transmit light.
What is translucent?
Approximately 299,792,458 meters per second (or about 186,282 miles per second) in a vacuum.
What is the speed of light?
The angle of incidence is equal to the angle of reflection.
What is the law of reflection?
Thinner in the middle and thicker at the edges, causing light rays to diverge after passing through it.
What is concave lens?
What are the colours of the spectrum?
What is red, blue, green, orange, yellow, violet?
Objects that do not allow light to pass through them and cast a shadow.
What is opaque?
Objects that give out light are said to be....
What is luminous?
What is the reflection of light?
What is When light bounces off a surface?
Used to correct vision problems by focusing light onto the retina, compensating for refractive errors in the eye
What is lens?
I separate light in different colours.
What is a prism?
Light travels fastest through what state of matter/
What is gas?
Objects that are not sources of light are said to be...
What is non-luminous?
How does a mirror reflect light?
What is by having a shiny and smooth surface?
A transparent object with at least one curved surface that can refract light.
What is lens?
Why does an apple appear red?
What is all other colours are absorbed and red is reflected?
Light travels the slowest in this medium.
What is solid?
