The diagram below represents a source, S, producing a wave pattern while moving at a constant speed.
Image shows S moving left towards point A with skewed waves towards point A.
If the source was to accelerate towards point A, what would happen to the wavelength of the waves nearest to point A?
A. The wavelength would decrease.
B. The wavelength would increase.
C. The wavelength would remain the same.
D. The wavelength would increase and then decrease.
A. The wavelength would decrease.
are you sure
Sorry for the confusion, let me clarify. When a source is accelerating towards a point, the wavefronts in front of the source become compressed, leading to a decrease in wavelength. So, the correct answer is indeed:
A. The wavelength would decrease.
