Your automobile antenna is 1m in length and is fixed at one end, free at the other. When you drive on an
uneven road, waves can be excited on the antenna. Compute the wavelengths of the four longest wavelength standing
waves that your antenna will allow.
for a standing wave i know these equations exist
λn =(2/n )*L
also A' = -A
furthermore, I know that the fixed end of the antenna could be considered to have infinite density
The Attempt at a Solution
the four longest wavelengths should be:
2/1 * 1 = 2 m
2/2 * 1 = 1 m
2/3 * 1 = 2/3m
2/4 * 1 = .5m
is this even close?
