Where do infrared and ultraviolet radiation sit relative to the visible band?
AInfrared sits above violet and ultraviolet sits below red
BBoth infrared and ultraviolet sit below the red end
CBoth infrared and ultraviolet sit above the violet end
DInfrared sits below red and ultraviolet sits above violet
Answer & Solution
Correct answer: D. Infrared sits below red and ultraviolet sits above violet
1. Frequencies just below the visible band are called infrared, sitting below red.
2. Frequencies just above the visible band are called ultraviolet, sitting beyond violet.
3. So infrared and ultraviolet sit on opposite sides of the visible band, one below and one above.
4. Placing both on the same side of the visible band contradicts this opposite arrangement.
