Verified answer
both problems are handled with speed of wave = wavelengthxfrequency
in the first wave, you have the wavelength = 3m/s / 2 Hz = 1.5m
if a wave of length 1.5 m travels for 5 s, it covers 7.5m
2) f= c/L = 5x10^4 m/s / 2.5x10^1 Hz = 2x10^3 m so the answer is B
1 answer B
2 answer B
Never thought about that too much
Interesting, I was wondering the same thing myself
I was wondering much the same thing
the answer is B and B I just did this for homework :D
