The string described in the problem introduction is oscillating in one of its normal modes. which of the following statements about the wave in the string is correct?
the wave is traveling in the +x direction.
a) the wave is traveling in the -x direction.
b) the wave will satisfy the given boundary conditions for any arbitrary wavelength lambda_i.
c) the wavelength lambda_i can have only certain specific values if the boundary conditions are to be satisfied.
d) the wave does not satisfy the boundary condition y_i(0; t)=0

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds
