Light Waves
A transverse wave composed of an oscillating electric field and a magnetic field that oscillates perpendicular to the electric field
What is an electromagnetic wave?
When light or sound waves bounce off of an obstacle.
What is reflection?
Light rays tend to bend when they travel through this type of object.
What is a transparent object?
The part of our body that signals are sent to once our eyes detect light.
What is our brain?
Cells in the eyes that are sensitive to color.
What are cones?
The light we see with our eyes.
What is the visible spectrum?
The angel of reflection equals the angle of incidence.
What is the Law of Reflection?
An object that makes all horizontal light rays converge to a single point.
What is a converging lens?
The thin transparent substance covering our eye.
What is our cornea?
The color we see when light contains all frequences.
What is white?
All the electromagnetic waves in creation.
What is the electromagnetic spectrum?
When a light wave enters an obstacle and bends in response to its change in speed.
What is refraction?
The type of lens that bends light rays outward.
What is a diverging lens?
This regulates how much light can get into our eye.
What is an iris?
The additive primary colors.
What are red, green, and blue?
The mnemonic device to remember the order of the colors of visible light.
What is ROY G BIV?
A cable that can transfer light over a great distance because when the light enters the cable it can not escape.
What is a fiber optic cable?
The shape of a converging lens.
What is convex?
Cells in our eyes that sense light hitting them and send electrical messages down the optic nerve to the brain, which decodes the messages and turns them into images.
What are rods and cones?
The subtractive primary colors.
What are yellow, magenta, and cyan?
The color with the longest wavelength.
What is red?
This is formed when there are many water droplets in the air and the sun shines on them and light is refracted through the water droplet.
What is a rainbow?
The shape of a diverging lens.
What is concave?
Two conditions that can develop when the eye's lens cannot be adjusted enough to make sure the image stays adjusted on the retina.
What is nearsighted and farsighted?
The color we see in the absence of light, when virtually no light is reflected.
What is black?
