Delta 2x n x
Delta2x was given .0005m & x=.00025m
Any1 know how to get the slope error and hair diameter etc.

Laser wavelength
Were we suppose to record the wavelength from the laser itself or do we calculate it?
Thanx

Re: Lab 7 Excel Execution
The wavelength was noted in the manual, i think its like 632 nm or something around there. not sure though so double check, and convert it to meters
Hair diameter by diffraction can be found using the equation we formulated in the lab prep

I couldn't find the hair diameter from diffraction (B). I tried using the m*lambda=b(x/D) but it didn't work. As for the lab prep, we found something like b = D*lambda/s, but what is that 's'?
thanks
thanks

Re: Lab 7 Excel Execution
what the heck is s for the hair diameter for diffraction?
the error for it is probably ( cant test it since i don't have s)
rel error = sqrt(((DeltaD/D)^2)+((Deltas/s)^2)) either that or
rel error = sqrt(((DeltaD/D)^2)+((Deltas/s)^2))*b

Cant edit....
i am an idiot S is slope
so B=D*lamda/slope
error = sqrt(((DeltaD/D)^2)+((Deltas/s)^2))*b

Re: Lab 7 Excel Execution
I have tried sooo many numbers and I can't get any slope errors to work on my excel sheet. Does anyone have any ideas what the error in slope should be?

error of slope!
does anyone have any idea how to get error of slope??? im lost and its the only thing i need..plzzz help! thanks

error in slope
Professor,
I've been plugging in values for the slope for a while now. You mentioned above that if might turn green because one or two of the points aren't on the line. This is not the case for my graph, any other ideas as to why it would not turn green?

error of Hair diameter from micrometer
hey guys, is there a forumula for this, or is it just a estimate? how did you guys figure an estimate?
thanks
thanks

.0001 or similar.
You can use the preliminary deviation from 0.

Can anybody help me with the questions regarding double slit interference. I am having a very difficult time understanding this.

The answer should be in question five of the prelab.

Re: Lab 7 Excel Execution
Can anybody explain to me the reasoning behind the "many slits, goin toward the diffraction grating" on the last execution sheet?
Much appreciated!
Much appreciated!
