Tough Trivia, 6/3/21

Today’s Entertainment question is about monomynous people: so cool that they only need one name. Some of them, however, we only know because of the groups to which they belong. So today, your challenge is to name the members of these groups: Santa’s eight (or nine) reindeer, Snow White’s seven dwarves, the five Spice Girls, and the three Powerpuff Girls. Bonus points if you can name them in alphabetical order.


Yesterday’s question: Light, or visible light, is no different from radio waves, x-rays, or any other part of the electromagnetic spectrum. The only difference is that this portion of the spectrum can be perceived by the human eye. The spectrum ranges from gamma rays, with wavelengths of 10^-16 meters (that is, ten to the negative 16th power) or frequency of 10^24 Hertz (ten to the positive 24th power), out to long radio waves (wavelengths of 10^8 meters, frequency at 1 Hertz). The colors of visible light are determined by their wavelengths (or frequencies). Can you list them from shortest to longest wavelength? Even better, can you list their wavelengths?

The answers:

Violet: 380 to 450 nanometers
Blue: 450 to 495 nm
Green: 495 to 570 nm
Yellow: 570 to 590 nm
Orange: 590 to 620 nm
Red: 620 to 750 nm



Ian’s Tough Trivia is a daily feature of this blog (Monday’s category is History; Tuesday is Arts; Wednesday is Science; Thursday is Entertainment; and Friday is Grab Bag). Each day, I post a tough question, as well as the answer to the previous day’s question. Simply comment on this post with your answer. I’ll approve the comments after the next question is posted. Sure, you can probably find the answers by searching the web, but what’s the fun in that?

And if you’ve got a favorite trivia question—or even just a topic for which you’d like to see a question—let me know! Reader participation is warmly encouraged.
