Q: A continuous wave (of sinusoidal pattern) is emitted from a source and a receiver stands 1000 meters away from the source. The receiver is able to measure the amplitude of the signal. Data from the receiver shows that the time between each maximum amplitude is 4 seconds. When the wave is graphically depicted, it is found that the distance between the adjacent highest and lowest amplitude is 3 cm. Which of the following is the speed of this wave?
A		1.5 cm/s
B		3 cm/s
C		0.75 cm/s
D		12 cm/s
