2 waves are traveling through a container of nitrogen gas. Amplitude of the first wave is 0.3 cm, and the second 0.9 cm. What is true about the two waves?
a. the energy of thee first wave is less than the second
b. energy of the first wave is greater
c. speed of the first wave is greater
d. speed of the first wave is greater
Since one wave is greater than the other one than the answer IS B, is that right?
