(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In room temperature air, which of the following sound waves would have the greatest energy associated with it?

A. A wave with lambda equal to 4.7 on

B. A wave with a frequency of 2.6 Hz

C. A wave which has a distance between adjacent nodes (1/2lambda) of 21mm

2. Relevant equations

v = f x lambda ?

maybe KE = 1/2mv^2 and PE = PGH?

no idea.

3. The attempt at a solution

I'm not exactly sure what an "on" is (referring to letter A, unless that's supposed to be inches? not sure).

A =

?

B = 2.6 Hz

already stated

C = 1633Hz, so above B.

343 = f x .021

343/.21 = 1633Hz

I know higher frequency = higher energy.. so I know The answer is either A or C. Since I don't know what an "on" is, I'm having trouble solving for it. Thanks.
