To increase intensity of a wave by a factor of 50, by what factor should the amplitude be increased?

This is also coming from the homework based on topics the video didn't cover. I know that power is proportional to amplitude squared, but what does this have to do with intensity?

same reference as before. You need to totally understand the difference between amplitude and intensity. Intensity is energy, the square of amplitude.
This is the problem with video instruction, I am fairly confident it was there, but you missed it, and there was no teacher to slap you when your mind drifted, or restated it so you listened.
Aha! Thank you! I got them both right now!
