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.

one-ninth

one-third

the same as

three times larger than

Wavelength is directly proportional to the speed of the wave, so if the wavelength of B is three times than that of A, then it's speed would be it's three time as well.

In short, Your Answer would be: Option D) Three times larger than

Hope this helps!

As speed is equal to wavelength * frequency

so, speed is directly propostional to wavelength keeping frequency constant..

in above question wavelength of B is 3 times  of wave A, so speed will also be 3 times

hope this helped
