I think it sounds pretty reasonable, as Ann Arbor is decently sized. 94 seconds sounds about right.

ahahha oops okay... now after plugging everything in the same way but with the new wavelength... v >= 99.79 m/s which leads me to t = 94.56 seconds Did I finally make it?

I thought there was 1,000,000 nm in a meter? 580 nm X 1 meter / 1,000,000 nm = 5.8 x 10^(-4) m

ok this time I did 5.8 x 10^(-4)(9.109 x 10^(-31))v >= hbar which lead me to v >= 9.975 x 10^(-24) plugged into D = rt 9436.4 m = (9.975 x 10^(-24))t t= 9.46 x10^(26) s And yes, this is my professor at University of Michigan, a weird dude.

I used the distance of ann arbor... But I guess I am supposed to use the wavelength of the light in this case? 580 nm for yellow light?

Alright, I used deltaXdeltaP >= hbar/2 and brought it down to 9436.4 meters(9.109x10^(-31)kg)v>=hbar/2 which gave me v >= 6.134 x 10^(-9) m/s so i plugged that back into D = rt 9436.4 = (6.134x10^(-9))t t = 1.54 x 10^12 seconds Is this right?

Am I supposed to use deltaXdeltaP = h ? What equation am I supposed to use? I see a lot of different equations for this.

Homework Statement Suppose I use visible (say yellow) light to observe an electron. Roughly speaking, I will then be able to localize the electron to a region about the size of the wavelength of the light. According to the uncertainty principle, I am now limited as to how well I know...

I outlined what I expected I would see in the OP, I'm just not sure if its completely right or I'm leaving something out. I don't think the light would return because the inner surface is DIFFUSELY reflective, therefore the light would scatter upon hitting the outside of the inner surface. Any...

Homework Statement Imagine yourself seated at the center of a spherical shell of radius 3 X 10^8 meters the inner surface being diffusely reflecting. A source at the center of the sphere emits a sharp pulse of light, which travels outward through the darkness with uniform intensity in all...
