Answer:
The electromagnetic spectrum encompasses a continuous range of frequencies or wavelengths of electromagnetic radiation, ranging from long wavelength, low energy radio waves to short wavelength, high frequency, high-energy gamma rays. The electromagnetic spectrum is traditionally divided into regions of radio waves, microwaves, infrared radiation, visible light, ultraviolet rays, x rays, and gamma rays.
Explanation:Exploration of the electromagnetic spectrum quickly resulted practical advances. German physicist Henrich Rudolph Hertz regarded Maxwell's equations as a path to a "kingdom" or "great domain" of electromagnetic waves. Based on this insight, in 1888, Hertz demonstrated the existence of radio waves. A decade later, Wilhelm Röent gen's discovery of high-energy electromagnetic radiation in the form of x rays quickly found practical medical use.This was on my notes
Answer:
B.) Greater than one
(at least I am pretty sure I am sorry if I am wrong I tried my best)
Explanation:
I think it is greater than one because it moves a short distance but it still is very helpful. The doorknob doesn't do much it just turns over and opens up a door. But, a doorknob CAN do much more. A doorknob can lock and keep things that you don't want inside out. It can also keep a door closed.
