A friend of mine send me these pictures showing three shadows during the day. The time of day was approx 11:45 and it was overcast. He asked me what was causing this effect. Basically you see three shadows. My hypothesis is that the overcast is diffusing the light causing scattering and the...

I think you are probably correct. What a sad state of affairs! None the less do you know of any video which would be simple enough to just basically show Boltzmann distribution in gravity well?

Could anyone suggest a simple video showing the Maxwell-Boltzmann distribution under the influence of a gravitational field? I trying to show a flat earther idiot how pressure gradients arise in a simple manner. Thank you all. DF

Do you have any references which I can explore further?

Wonderful...Why? What are the physics?

I just wanted the basic mechanism explained, or at least a reference. Should I look under defraction, reflection or perhaps slit experiment ?

Yes. I didn't know how to phrase the question. I thought I could get a more succinct and definitive answer here.

Could someone explain to be the reason why size of the hole or grating in the case of Faraday cage is what determines if the screen or grating is opaque or transparent? I'm pretty sure it has something to do with interference patterns in classical physics. Thank you all in advanced.

I'm curious if someone help me understand why the electric and magnetic forces are IN PHASE at right angles to one another? Should they not be 90 degrees out of phase in order to conserve energy? I do understand they are in phase but why? Thank you all for your time. Merlyn.

Ok. Here is worked out example. ##\int_0^L e^{i2 \pi nx/L}e^{-i2 \pi mx/L} \, dx \rightarrow \int_0^L e^{\frac {i2 \pi nx + -i2 \pi mx} L} \, dx \rightarrow\int_0^L e^{\frac {i2 \pi(n-m)x} L } \, dx## ##a= \frac {i2 \pi(n-m)} L## ##\int e^{ax} \, dx = \frac 1 a e^{ax} \rightarrow## ##\int...

##e^(i2π(n-m)x)/L## better?

Sorry...I will retype later tonight. Didn't see menu bar.

I'll look up my integral tables tonight and see. Thank you so far.

Right..But that really does not help in this case. All you get is ##e^(i2pinx-i2pimx)/l## right? and ##e^(i2pix(n-m))/l##

Thank you so much in advance for your time. It's mainly collapsing the the two 'e' into one. The definite integral I think I can handle. If you could show me a worked out example I would REALLY appreciate it. I'm sure I am just missing a step here. It's probably my stupid brain. Sorry for all...
