An Assessment: Think Pair Share Best procedures: read quietly to yourself (so you don’t give any subconscious clues) As the instructor, we read it too, for timing, then ask if anyone needs more time If not, it’s time to vote simultaneously—use your fingers, right in front of your chest so others don’t see (anonymous)

If you were going to design a pair of glasses for seeing animals at night, you would want them to convert X-ray photons to optical photons. infrared photons to optical photons. optical photons to UV photons. infrared photons to X-ray photons.

Compared to optical photons radio photons have a longer wavelength. X-ray photons have a larger frequency. infrared photons have a smaller energy. All of the above. None of the above.

Which statement is true? Radio waves have longer wavelengths than and travel the same speed as x-rays. Visible light has a shorter wavelength and lower energy than infrared light. Ultraviolet light has more energy and a longer wavelength than x-rays. Radio waves have less energy and travel slower than visible light. Infrared light has shorter wavelengths than and travels the same speed as visible light . 0/0
