The whole question is talking about the amplitude of a wave 
that's transverse and wiggling vertically.
Equilibrium to the crest . . . that's the amplitude.
Crest to trough . . . that's double the amplitude.
Trough to trough . . . How did that get in here ?  Yes, that's 
                               the wavelength, but it has nothing to do
                               with vertical displacement. 
Frequency . . . that's how many complete waves pass a mark 
                       on the ground every second.  Doesn't belong here.
Notice that this has to be a transverse wave.  If it's a longitudinal wave,
like sound or a slinky, then it may not have any displacement at all
across the direction it's moving. 
It also has to be a vertically 'polarized' wave.  If it's wiggling across 
the direction it's traveling BUT it's wiggling side-to-side, then it has 
no vertical displacement.  It still has an amplitude, but the amplitude 
is all horizontal.

radio waves,X-rays,
Explanation:
In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
 
        
             
        
        
        
<span>The answer is 45 miles per hour or even less. Most crashes occur at a speed of 45 miles per hour or even less, and most of these accidents occur close to our homes. These crashes may also be caused by different factors, such as being drunk or sudden occurrences that are not controllable, which is why it is best to precede with caution when driving at crowded areas.</span>
