Lab 9 Execution

Let's get the ball rolling please

How are you guys getting the wavelength (m)?
- i tried 1/ {(1/2^2)-(1/n^2)}

with the value of (1/2^2)-(1/n^2) i thought that was (1/wavelength) which i tried entering into the appropriate column but only one lights up o.o

any ideas on this? my values of m won't light up either, did you guys account for a distance difference?

thanks

d*sin(theta)= m(wavelength). but my answers arent coming out correct. can someone explain in better detail how to get the wavelength?

Does anyone know how to find the error of the slope?

(1.8955E-6)*sin(your angle)=wavelength (m=1)

0.0254/13400=1.895E-6

does anyone know how to solve for error of slope besides just putting in random numbers. Is there a calculated value i can use?

does anyone knows how to find delta (1/lambda) and error of slope

On excel, it asks for positions, which me and my partner have changed the numbers, meaning we subtracted the distance from the distance where the gas tube was to have the position, those numbers i used for the first table positions, but then wat do we put in for x the table below??

For x, or the positions of the different colors, just take the difference between your right position and left position and put it into meters.

anyone know how to find relative error in x/2y or error in 1/lambda? thanks

To find the error in the slope, you take the calculated relative error of x/2y and multiply it by your calculated 1/lamdba

sry that was for delta 1/lambda

Hey guys

I need help in finding

* Relative error x/2y

* how to find the degree

thanx

For degrees, you do tan-1 of your x/2y value

thanx

I only need Relative error x/2y now

Hi

How do u find these

hey the slope is the exact # given on the graph after it it plotted. but, i was wondering how to get error of slope. or if we just make up a number how do we do that? thankss!
