Question

Two waves are travelling through the same container of nitrogen gas. Wave A has a wavelength of 1.5m. Wave B has a wavelength of 4.5m. The speed of wave B must be __________ the speed of wave A.

Question 8 options:

One-third


The same as


Three times larger than

Answer 1

C because do 1.5 times 3

Answer 2

Answer is the same as.

The speed of wave B must be same as the speed of wave A. Speed of a wave depends on the medium through which it travels. Both waves A and B are travelling in the same medium, nitrogen gas. Therefore, speed of wave A and wave B will remain the same. In the same medium and same conditions the speed of waves remain constant.
