-- If the frequency of a wave is too high for our eyes to detect it ... but not <u>too too</u> high ... we call it an <em>ultraviolet </em>wave.
-- If the wave's frequency is even higher than that, we call it an <em>X-ray</em> wave.
-- If the wave's frequency is even higher than that, we call it a <em>Gamma Ray </em>wave.
On Earth, 1 kilogram of mass weighs 9.8 newtons or 2.2 pounds.
9.8 newtons = 2.2 pounds
(9.8/2.2) newtons = 1 pound = 4.45 newtons
(2.2/9.8) pounds = 1 newton = 0.225 pound
5 pounds = (5 x 4.45 newtons) = 22.2 newtons.
22.2 newtons is more than 10 newtons, so
5 pounds is more than 10 newtons.
