100
Light travels in a straight line as a(n)
electromagnetic wave
100
Mirrors _____ light and lenses ______ light
Mirrors REFLECT light and lenses REFRACT light
100
This wave type has the lowest frequency that we know of. Their wavelength can be as long as a planet and as short as a meter. They can transmit through walls due to this.
Radio waves
100
These are the colors of the visible light spectrum and combined create white light
Red Orange Yellow Green Blue Indigo Violet
100
This kind of light behavior causes the Moon to shine
Reflected
200
If an object lets some light pass through, it's called ______.
translucent
200
This is object breaks up white light in to the visible light spectrum through refraction
A prism
200
This part of the spectrum is directly related to thermal (heat) energy. It has a lower frequency compared to visible light, and it is used in remote controls.
Infrared waves
200
This color has the highest energy, highest frequency, and shortest wavelength
violet
200
Eye glasses work because they _____ light to adjust the _____ point that is present in your eye.
they REFRACT light to adjust your FOCAL point
300
The DISTANCE light travels in one year is called _____
a light year
300

A mirror that is curved inward like a bowl and makes you look upside down is called this.

a concave mirror

300
This part of the spectrum is able to transmit easily through the atmosphere, and therefore used primarily as a communication tool to probes and space stations. It has a longer wavelength than radio waves but a shorter wavelength than infrared.
microwaves
300
What colors are reflect and which are absorbed in a blueberry
Reflected: Blue, Absorbed: ROY G _IV
300
If an object creates a shadow, the object is _______.
opaque
400
Frequency is equal to ________
# of complete waves per second
400

These lenses are thicker in the middle area and are relatively thin at the sides. The edges of the lens are curved outward.

convex lenses

400
These rays cause sunburn and have a slightly higher frequency than visible light
UV (ultraviolet)
400
_____ is created by all colors in the spectrum being absorbed. _______ is created by all colors in the spectrum being reflected.
Black, White.
400
Objects that are opaque cause one or two light behaviors
reflect and/or absorb
500
The lower the frequency the _________ the wavelength and the _______ energy.
the LONGER the wavelength and LESS energy
500
A telescope uses __________ to look at faraway objects, like stars and planets.
convex lenses
500
These waves have the highest frequency that we know of. They can kill small microorganisms off food, they can treat cancer by destroying cancerous cells, and in the Marvel universe they created the Hulk.
Gamma waves
