Was my other post deleted for any particular reason? Here it is again
1)Doubling the amplitude of a wave will double the amount of energy the wave can transfer.
2)What happens when a wave reaches the boundary of a new media?
it would reflect back
I agree on the first, on the second I disagree. For the medium to be undisturbed, the two waves have to completely cancel.
On the third, no. How is energy related to amplitude?
On the fourth, the answer is complicated. If the new media has a wave resistance exactly the same as the intial medium, the wave moves on thru. If not, then some of the energy is reflected back, some is transmitted. If the new medium has zero or infinite resistance, then all of it will be reflected back.
On the third, waves with greater amplitudes transfer more energy
For the 2nd, is it A? What's the difference between B and C
On the 4th:
C)either A or B
D)it would stop
Since you gave that explaination, would it be C?
C on the fourth.
Now on second, opposite amplitudes add to zero.
On the third, Energy is proportional to the square of amplitude.
Ok, I think I understand the 3rd. It doesnt double, it quadruples, so it's false
