Ohh... I see. Thank you

Awesome! Thank you.

Homework Statement Find the velocity v of a general point on a plate rotating at 800 rpm which is r meters from the center. This is literally a copy and paste job. Homework Equations period = T = 1 / f ; f = frequency The Attempt at a Solution This is what I did please tell me if it is...

Ok, I figured it out. First off my math was bad when I came up with the 800 nm. I only multiplied by d rather than 2 d had I done this I would have found a wavelength of 1600 nm. Still not the right answer but it is the right equation. It then occurred to me that I have a variable that I can...

Homework Statement http://lon-capa.bd.psu.edu/res/psuerie/gwb6/physics/optics/e1p4.png A thin 200nm film of oil (n = 2.0) floats on water (n = 1.33). To a normal human, what wavelength will the film appear when viewed from above (nearly perpendicular to the film)? Homework Equations for...

Ahhh. I plugged in the old v. thanks for your help.

Homework Statement Two passenger trains A and B, each 240 m long, pass a 60 m long railroad platform in Winnepeg. The trains are moving in opposite directions at equal speeds of 0.665c with respect to the ground. Train A is traveling west and all tracks are perfectly straight. A) From the...

And the hand meets the forehead... It states the 6th line of the Balmer series not the sixth quantum level. Thank you for your help, I had a feeling it was something simple.

Homework Statement Compute to three significant figures the wavelength of the sixth line in the hydrogen Balmer series. Homework Equations 1 / lambda = R * ( 1/ n_final^2 - 1 / n_initial^2 ) R = Rydberg constant = 10973731.57 m^-1 lambda = wavelength The Attempt at a Solution I set up the...

Thank you. I appreciate you taking the time to respond. I am unsure where I made my error. My initial thought is that I might have been in radian mode, but I suspect my result would have been much smaller had that been the case. Whatever the reason; it is reassuring to know that I do indeed...

Homework Statement A Helium laser, λ = 588 nm, shines on double-slits separated by 1.80 mm. An interference pattern is observed on a screen at a distance R from the slits. The point C on the screen is at the center of the principal maximum of the interference pattern. The point P is the point...

A question has occurred to me during preparation for a Physics exam. My textbook does a good job of discussing a capacitor charged equal but opposite. But I want to take it a step further. My question is how to calculate the E field between 2 plates of opposing charge that have unequal...
