Radio waves have the longest wavelengths and lowest frequencies, and are used by televisions and radios to receive signals. Microwaves have slightly shorter wavelengths than radio waves. Infrared waves have wavelengths shorter than radio waves but longer than visible light, and are used to heat objects as they are absorbed by cameras to create thermograms. Visible light has the perfect wavelengths and frequencies to be seen by the human eye and makes up the rainbow. Ultraviolet light has shorter wavelengths than visible light and causes things to glow purple. X-rays have wavelengths just shorter than ultraviolet light and can pass through soft tissues but not hard tissues like bone. Gamma rays have the shortest wavelengths and highest frequencies and are released by supernovas and nuclear
2. Radio waves. Longest waves
and the longest frequency.
A tv uses radio
waves to pick up
signals
A radio does
the same.
3. Micro waves have a slightly lower length and frequency than radio
waves
Both of these use radio waves
4. Infrared waves
Wavelengths shorter than radio but bigger than visible
light
Both put of inferred waves to heat up
things
The infrared waves
hit the cameras to
form a thermogram
The snowman is melting because the
inferred waves/ heat is hitting him
and heating the snow
5. Visible light wave lengths and frequency perfect to
see the light
The rainbow. Purple has the lowest
frequency and red has the highest
