What gas? Gas is an invisible form so I don't see how it would have a "defined structure".
Answer:Hydrostatic
Explanation: I think this is the answer, not sure. Sorry
Answer:
Explanation:
wavelength, λ = 3.4 m
wavelength, λ' = 3.3 m
Speed, v = 340 m/s
f = v / λ = 340 / 3.4 = 100 Hz
f' = v / λ' = 340 / 3.3 = 103.03 Hz
Frequency of beat, n = f' - f = 103.03 - 100 = 3.03 Hz
<em>D. Less luminous than those on the right []</em>
