Wave Motion
Wave motion
A wave is nothing more than a disturbance that moves from place to place in some medium, carrying energy with it. Since the behavior of waves is so closely related to the concept of oscillations, that is a good place to start.
There are many examples of simple oscillations, but a very good one is that of an object attached to the end of a spring. Assume that the other end is held fixed, perhaps by a clamp. Suppose the spring hangs vertically and slowly lowers the object until it becomes stationary. The spring is now stretched enough for its upward pull to balance the weight of the object, which at that location is in equilibrium. Now disturb the object by lifting it a short distance above that point and letting go. The object then begins to oscillate vertically as it first falls, until the spring stops it and pulls it back upward to the original position, then it falls again, etc. The energy in the oscillating motion came from the original disturbance, which in this case moved the object to a position above the equilibrium point. At that instance, the object was at its maximum displacement whose size is the amplitude. The larger the amplitude, the greater the energy in the motion.
If we hang a duplicate object and spring side-by-side with the first one, but without the two being in contact in any way. If we disturb the first object, it oscillates just as before and the second object remains stationary at its equilibrium position. However, the situation becomes different if we connect the two objects with a rubber band and then disturb only the first object. It begins to oscillate as before, but soon the second object starts to oscillate also. The rubber band allows energy to transfer to the second object, which will move with the same frequency as the first oscillation. We can make the experiment more complicated if we use a large number of springs hanging in a row, with each object connected to the one before and after it with rubber bands. If only the first object is disturbed, the oscillation will pass its energy through all the springs. After the energy has been transferred to the next few springs, the first spring will become still with its object back at its equilibrium point. This demonstrates exactly how a disturbance can move as a wave through a medium. In this example, the medium is composed of the objects on springs, which act as coupled oscillators.

Use the equation:
v = f*lambda
Where v is the velocity of propogation of the wave (in m/s), f is the frequency (in Hz), and lambda is the wavelength (in m) of
using frequency you should be able to find velocity, and then from there its just the simple Newtonian motion equations.The kind of motion depends on the type o
transverseI suppose that it would be transverse waves, seeing as the median that those waves travel through goes up and down as the wave travels forward.
Yes. One way to look at it is to say the antenna radiates, and this radiation has destructive interference with the incoming wave.
