Across
- 5. This is a low frequency, low energy wave that is associated with heat. Infrared waves can be converted to colors that allow people to see things in the dark or see through wall.
- 7. These are mostly associated with communication. The are the lowest frequency and lowest energy of all EM radiation. They are used for radios, walkie talkies, and cellphones. Bluetooth uses this type of wave.
Down
- 1. all the colors of light that can be seen. ROYGBIV. Visible light has frequencies and wavelenghts in the middle of the EM spectrum.
- 2. second highest frequency EM, 2nd shortest wavelenght. Used to take images of bones.
- 3. commonly used in blacklights. These rays from the sun can be dangerous to people.
- 4. The appliance you used to cook things really fast is named because it uses these relativity low energy (low frequency) waves to heat the water molecules inside the food.
- 6. shortest wavelength, highest frequency EM radiation. They have the most energy of all EM radiation. Associated with nuclear energy
