Light and Color
100
This is the only electromagnetic wave that can be seen.
What is visible light.
100
This electromagnetic wave has the least amount of energy/frequency.
radio
100
In this interaction of light waves light bounces off of objects.
What is reflection.
100
It's hard to tell exactly where a fish is in water because of ____________.
refraction
100
Light passes through this type of matter perfectly.
What is transparent matter.
200
An electromagnetic wave consists of these two fields.
What are electric and magnetic fields.
200
These electromagnetic wave has the shortest wavelength and highest energy/frequency.
gamma waves
200
In this interaction of a light wave light bends, causing rainbows and optical illusions such as the ruler with water.
What is refraction.
200
We see ourselves in mirrors because of ___________.
light
200
Some light transmits through __________ matter, but in ____________ matter no light can be transmitted.
What is transparent or translucent and opaque.
300
An electromagnetic waves are ____________ waves.
transverse
300
This electromagnetic wave gives us sun burn.
ultraviolet rays
300
We can not see our reflection is rough objects because the light doesn't reflect at one angle. Instead the light _____________.
What is scatters.
300
Why does a spoon look bent in water?
refraction
300
In a strawberry this wavelength is reflected.
What is red.
400
The transfer of energy as electromagnetic waves.
What is radiation.
400
These types of electromagnetic rays are slightly dangerous. These waves produce heat.
What are infrared waves.
400
When light energy gets soaked into an object.
absorption.
400
This contraption lets you look around walls, corners or other obstacles. Submarines have these so that people inside can see what is on the surface of the water.
What is a periscope.
400
For the shade of black: red, orange, yellow, green, blue, indigo and violet is ____________.
What is absorbed.
500
Visible light takes this amount of time to reach the Earth.
What is 8.3 minutes.
500
Ultraviolet rays gives us this one good side effect.
What is Vitamin D.
500
____________ objects reflect light.
opaque
500
Light refracts as it passes through our atmosphere. This wavelength is the first to scatter because it has the most energy.
What is the blue wavelength of light.
500
What happens to the wavelengths of light when we see a blue translucent object?
All colors are absorbed and blue is transmitted.
