What Is Light?
This happens when light bounces off a surface.
What is reflection
The distance from one wave peak to the next.
What is wavelength?
Light travels fastest in this.
What is a vacuum (or space)?
When light bounces off an object.
What is reflection?
White light is made of many of these.
What are colors?
A smooth surface like a mirror causes this type of reflection.
What is regular reflection?
How fast a wave vibrates.
What is frequency?
True or False: Light travels slower in water than in air.
What is true?
When light passes through a material like glass or water.
What is transmission?
The colors of the rainbow in order are called this
What is the visible spectrum?
A rough surface causes light to scatter in many directions.
What is diffuse reflection?
The height of a wave from the middle to the top.
What is amplitude?
Light slows down when it passes through this kind of material.
What is a medium?
When light is taken in by a material and changed into heat.
What is absorption?
This tool separates white light into colors.
What is a prism?
We see objects because light does this off them and into our eyes.
What is reflect?
Light waves are this type of wave (not mechanical).
What are electromagnetic waves?
Bending of light when it slows down.
What is refraction?
Bending of light as it moves from air into water
What is refraction?
Objects appear black because they absorb this.
What is light?
Light is part of a larger group of waves called this.
What is the electromagnetic spectrum?
When wavelength gets shorter, this gets higher.
What is frequency?
Light travels slower in water than in air because water is this.
What is more dense? (or What is optically denser?)
A clear object that lets most light pass through.
What is transparent?
The color of light with the longest wavelength that humans can see.
What is red?
