BASICS
I have longer wavelengths than infrared but shorter wavelengths than radio waves.
What is microwave?
The speed that all electromagnetic waves travel at in a vacuum.
What is the speed of light?
Doctors may use this type of wave to look at broken bones.
What are x-rays?
I am the smallest range of wavelengths on the electromagnetic spectrum.
What is Visible Light?
I am used to treat cancer.
What is gamma rays
The primary colors of visible light.
What are red, green, and blue lights?
This is the frequency of an electromagnetic wave with a short wavelength.
What is high frequency?
This type of wave is often used in microwave ovens to heat food.
What are microwaves?
I am what you see when all colors of visible light are reflected.
What is white?
The color of visible light that is reflected off a green object.
What is green light?
This type of signal changes smoothly and can take on any value within a range.
What is an analog signal?
TV remotes often use this type of wave.
What is infrared?
This is the correct order of visible light from longest wavelength to shortest wavelength.
What is red, orange, yellow, green, blue, indigo violet?
This is the reason ultraviolet light can damage skin cells more easily than visible light.
What is higher energy?
This type of wave is often used in Bluetooth and WiFi connections.
What are radio waves?
The longest, least energetic part of the EMS.
What are radio waves?
This is the correct order of the electromagnetic spectrum from longest wavelength to shortest wavelength.
What are radio, microwave, infrared, visible, ultraviolet, X-ray, gamma?
Visible light fits on the electromagnetic spectrum between these two types of waves.
What are infrared and ultraviolet?
These waves carry energy through space without moving matter from one place to another.
What are electromagnetic waves?
Computers use this type of signal because it is easier to store, copy, and transmit without loss.
What is a digital signal?
