Question

The electromagnetic _____________ is the range of all possible frequencies of electromagnetic
radiation. A common name for the electromagnetic radiation that humans can see is
______________ light. What humans call white light is actually made up of all of the colors in
the ______________. The entire range of frequencies, however, extends from far below to far
above what can be seen the human eye. Light is energy that travels like a _____________. A
very low frequency might have a __________________ that is longer than a
_________________, whereas a very high frequency might be shorter than an __________.
Humans use many parts of the electromagnetic spectrum that cannot be seen. For example, a
_____________ signal will pass through you like you are a window, but a proper antenna can
capture the signal so it can be transformed into something you can hear. Other frequencies are
used in medicine. For example, _____________ are used to check for broken bones because
they partially pass through you. But be careful of the _______________ range! Frequencies in
this range can cook you just as they cook your food. Your skin can be damaged by __________
frequencies, if you do not take care. But ____________ can help you feel warm, even if you
cannot see it.

Answer 1

surely you can fill in at least some of the blanks.
google electromagnetic spectrum for a start (which also fills in the first blank!)
