On second thought, no actually. Truthfully I doodled that after looking at some the book's pictures of light bouncing off a droplet. Is this better? It looks like it makes more sense this time around.

Here's the diagram I drew for the problem. I had it on paper so I re-drew in Paint. Now I'm have doubts if that's even right, heh.

Homework Statement Light consisting of a mixture of red and blue light enters a 40°, 70°, 70° prism along a line parallel to the side opposite the 40° vertex. The index of refraction of the prism material for blue light is 1.530, and for red light it is 1.525. What is the angle between the two...

Yes it does. Thank you very much!

I imagined the speaker on the ground, and then imagine the 'sphere' of sound in all directions. I didn't see it as a full sphere, so I thought the first equation wasn't right. Then I guessed it might just be a circle.

Homework Statement A speaker emits sound waves in all directions, and at a distance of 28 m from it the intensity level is 73 db. What is the total power put out by the speaker, in watts? ( reference intensity I_{0} is 1.0 × 10-12 W/m2.) Homework Equations P= I*A I = I_{0}*10^{B/10} SA =...

I think I got it now after doing some thinkingAt the bottom, only the weight matters, right? so T = m1*g At the middle, we have the weight and half(?) the cord so T = g*(m1 + 0.5m2) At the top, we have the weight and full-cord so T = g*(m1 + m2) Then I can solve for the respective wave...

After doing some force analysis, would it make sense to say that T = m1*g + µ*m2*x?

Homework Statement A hanging cord is attached to a fixed support at the top and is 78.0m long. It is stretched taut by a weight with mass 21.0kg attached at the lower end. The mass of the cord is 2.20kg . A device at the bottom oscillates the cord by tapping it sideways (Do not neglect the...
