These questions will help you to see the light. Take the quiz and see if you shine brightly.
The cone cells that detect colour need more light than your rod cells do. That’s why you can’t see colour in the dark!
The rods and cones that turn light into nerve signals are found in the retina on the back of the eye.
Red light is on the outside of most rainbows. If you get a double rainbow though, the red will be on the inside of the second rainbow!
We orbit the Sun at a distance of about 150 million kilometres. Light moves at 300,000 kilometres/second. Divide these and you get 500 seconds, or 8 minutes and 20 seconds.
True. Scientists aren’t sure why scorpions fluoresce or glow under UV light. It might help them hunt, or find a mate, or to sense when they’re in in sunlight during the day.
Congratulations! You are a real science whiz!
Oh dear! Better brush up before the next quiz!
