7 Infrared RadiationCreates heat. It has the longest wavelength.
8 Ultraviolet Electromagnetic waves UV the Hidden Dangerelectromagntic waves UVcauses sunburns and eye damage (UV) and has the shortest wavelength. This is the most dangerous type of radiation. Sunscreen helps protect us from this type of radiation.
9 electromagnetic waves that create color. ROY G BIV Visible Lightelectromagnetic waves that create color.ROY G BIVR= longest wavelengthV= shortest wavelengthApples are red because they absorb every color but red. They reflect red so you see red.White reflects all color. It absorbs nothing.Black reflects no color. It absorbs it all.What is Light? Video clipapple light reflection video
11 Reflection of LightAs these electromagnetic waves travel through the atmosphere to earth, some of them are reflected and some are absorbed by particles in the atmosphere.Reflection of light in all directions is called scattering. This causes the sky to be blue. The particles in the air scatter the blue and violet wavelengths. So we see blue.
12 Greenhouse EffectThe greenhouse effect is caused by the reflection of light back and forth between Earth and the blanket of gases surrounding the Earth.This is what keeps Earth at a comfortable temperature for all the living organisms on Earth. Without it we would freeze to death.
