The part of the electromagnetic spectrum has the highest frequency.
What is Gamma Waves?
Electromagnetic waves are this type of wave
What is transverse?
The electromagnetic spectrum is organized by this feature of the wave.
What is wavelength, or frequency?
Combining equal amounts of the three primary pigments produces _.
black
The part of the spectrum used to look at bones.
What is X-rays?
The part of the electromagnetic spectrum that is often detected as heat
What is infrared?
The part of the electromagnetic Spectrum has the smallest or lowest frequency.
What is Radio Waves?
The color with the longest wavelength.
What is red?
Unlike longitudinal waves, EM waves are able to travel through empty space also known as this
What is a vacuum?
Mixing the primary colors green and red produce this secondary color
yellow
The part of the spectrum we use to treat cancer
What is Gamma Rays?
The part of the electromagnetic spectrum that help our bodies make Vitamin D but can also cause sunburns
What is ultraviolet?
Light amplification by stimulated emission of radiation is known as _ light.
laser
Found between infrared and ultraviolet on the EM spectrum
What is visible light?
As the frequency of a wave increases, the wavelength _______ .
What is decreases or becomes smaller?
Mixing the secondary pigments yellow and Cyan produce this primary color of pigment
green
The part of the spectrum do we use to sterilize medical equipment.
What is Ultra Violet?
The part of the electromagnetic spectrum that is used to look at soft tissue in the body (MRIs and CAT scans).
What is X-Rays waves?
The part of the electromagnetic spectrum that can cause skin cancer.
What is ultraviolet waves?
A transparent object _ almost all of the light that strikes it.
transmits
This occurs when light passes through a prism allowing a rainbow to be seen on the other side
What is refract or refraction?
Any two colors of pigments that combine to make black are this type pf pigments
complimentary
The part of the spectrum do we use to listen to AM/FM stations in the car
What is radio waves?
White light passing through a prism separates into colors because of the differences in the _ of each color of light.
Frequency or wavelength
The most dangerous part of the electromagnetic spectrum that can cause radiation poisoning and death even is moderate amounts.
What are gamma waves?
Where electromagnetic waves come from
What is the Sun or Stars?
Because light travels in a straight line and casts a shadow, Isaac Newton hypothesized that light is
a stream of particles
When combined complimentary colors of light produce this color of light
white
Which of the following occurs as a light wave bends when it passes from one medium into another?
refraction
Cellular telephones utilize
Microwaves
Newton’s prism experiments showed that white sunlight is made up of
all the colors of the visible spectrum.
A mirage, or distorted image, can be caused by the _ of light as it moves into layers of hotter and hotter air.
refraction
Photons travel outward from a light bulb in
all directions
This is the process that separates white light into colors
dispersion
