If two sources of slightly different frequency and different amplitudes create waves at the same time, the resulting superposition of those waves can be described as
A)
a wave with an amplitude that varies from zero to an amplitude equal to the sum of individual amplitudes. This variation would occur at a frequency equal to the difference in source frequencies.
B)
a standing wave with an amplitude equal to the average of the amplitudes of the individual waves and a frequency equal to the average of individual frequencies.
C)
a wave with an amplitude that varies from an amplitude of the difference in individual amplitudes to an amplitude equal to the sum of individual amplitudes. This variation would occur at a frequency equal to the difference in source frequencies.
D)
a standing wave with an amplitude equal to the sum of the amplitudes of the individual waves and a frequency equal to the average of individual frequencies.
E)
a standing wave with an amplitude equal to the product of the amplitudes of the individual waves and a frequency equal to the sum of individual frequencies.
