Electromagnetic Spectrum Quizzes Online & Trivia

There are two types of waves that are shorter than visible light. The answers to this question are C and D. Are you familiar with what gamma rays are? These are similar to what you would see in x-rays. Gamma rays are known to be very active radiation which means that if they would pass through certain particles, they will cause the radicals to become charged. Ultraviolet ray or UV ray is something that a lot of people are familiar with. This comes from the sun and it makes up about 10% of the sun’s rays. UV light is used in order to sterilize different products and materials. People should not become exposed to this too much as it may cause some skin diseases.

The correct answer to this question is A, infrared. It was discovered in 1800 by William Herschel and is apart of the electromagnetic spectrum, which extends from long wavelength to microwave range. Infrareds have longer wavelengths than the visible eye, which why they are unable to be seen by the human eye. They extend from 700 nanometers to 1 millimeter. Infrareds are useful in military, hunting, and law enforcement industries. Used mainly through night vision devices, which allow people to animals to be observed without anyone knowing. There are thermal cameras, which can also detect heat loss. It can identify changes in blood flow to the skin.

Out of the waves on this list, ultraviolet and gamma rays have shorter wavelengths than what we can see with the human eye. Ultraviolet light is what’s responsible for tanning in the summer, as well as sunburns. It tends to be harmful to living tissues, but in small doses (such as the incidental slow tan that may happen as you walk short distances often in the summer or spring) it’s not that bad. UV light can also cause things to florace, which is why it’s used in black lights. Gamma rays, on the other hand, are another kind of radiation. This usually results from a radioactive decay from a radioactive nucleus. Both have uses and disadvantages in human lives, so they are often talked
