Question

Which sequence shows the different types of electromagnetic waves arranged in an increasing order of their frequency?

Answer 1

Select one:

a. Wave 1, Wave 4, Wave 3, Wave 2

b. Wave 2, Wave 1, Wave 3, Wave 4

c. Wave 3, Wave 4, Wave 1, Wave 2

d. Wave 4, Wave 3, Wave 1, Wave 2

D is the correct answer!

Answer 2

There is no sequence on your list that shows anything like that.

If you find a sequence that purports to do it, check and see that it
has radio first and gamma rays last. That sequence is a good bet,
although there can't be any guarantee until you all check all the others
in the middle.
