An Assessment: Think Pair Share

1. 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)

2. 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.

3. 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.

4. 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
