Wavelength ranges from 10^3 to 10^-12 meters on a logarithmic scale. Range includes Radio, Infrared, Visible, Ultraviolet, X-ray, and Gamma-ray light.
Radio waves range from things the size of a soccer field (10^2 meters), to the size of a house (10 meters), to the size of a baseball (10^-1 meters). The temperature of something glowing at radio wavelengths is about -273˚C. Sources include AM radio, FM radio, and microwave ovens.
Alma Receives wavelengths between 10^-2 and 10^-3.
Infrared waves range from things the size of a period (10^-3 meters) to things the size of a cell (10^-5 meters). The temperature of something glowing at a wavelength of 10^-4 m is about -248˚C. Things that glow in infrared light include humans. 
The human eye receives visible light between 10^-6 and 10^-7 meters. Visible wavelengths range from things the size of bacteria to things the size of viruses. The temperature of something glowing in visible light is about 5720˚C. The sun glows in visible light.
Ultraviolet light ranges from 10^-7 to 10^-8 meters.
X-rays range from things the size of proteins (10^-8 meters) to things the size of water molecules (10^-10 meters). X-ray machines produce x-ray light.
Gamma-rays are things the size of an atom (10^-8 meters) and smaller. The temperature of something glowing in gamma rays is about 10,000,000˚C. Radioactive elements produce gamma-rays.</a></label><br><a href="https://cdn.masto.host/astrodonsocial/media_attachments/files/112/950/999/299/826/753/original/e6aef810b74aa9fe.jpg" rel="external">https://cdn.masto.host/astrodonsocial/media_attachments/files/112/950/999/299/826/753/original/e6aef810b74aa9fe.jpg</a></li></ol></footer></blockquote>

Two years after a cyber attack, ALMA (the Atacama Large Millimeter/submillimeter Array) re-launched the ALMA mini-site for kids.
I'm glad it's back online. It has lots of great content and activities, available in both English and Spanish, including my favorite electromagnetic spectrum chart.
