I am currently studying wave-particle duality. However, at the moment I do not see how the Bohr Model is connected to this topic. I know that the Bohr Model failed to recognise various aspects of the atom and that it works only for single atoms e.g. Hydrogen, but what did it fail to do when it...
Homework Statement
An aerial feeder cable (characteristic impedance 75Ω) is connected to a long cable of characteristic impedance 120Ω. If a 100μV signal is received at the aerial, calculate the amplitude of the signal transmitted into the second cable. What fraction of energy is carried by...
When swimming underwater, why does sound from above the surface sound very faint?
I know that the answer to this may be simple, but I just can't put my finger on the answer. I know that sound travels faster in water then it does in air, does this fact have anything to do with it?
Thanks!
