Can someone please help me with this,

the lab seems easy but I keep messing it up, if you could help I would appreciate it, please

can you please check my work

Please take a look at the manual

Example: please take a look at the lab manual and then look the example

https://www.coursehero.com/u/file/69214642/Lab-27-Diffractiondocx/?justUnlocked=1

you can use the example if needed but I prefer new numbers please but similar steps and rang

Step-by-step explanation d ( nm ) = 2000 nm ( NOTE : d can't be as large as 1000000 nm, hence a reasonable value of 2000 nm is used here ) L = 310 mm Order, n Location, Xn ( mm ) Angular location, On ( degrees ) * ( nm ) = tan" (xn / L) = d sin On / n +2 250 tan-1 ( 250 / 320 ) 2000 sin 38 / 2 = 38 = 615.66 +7 120 tan-1 ( 120 / 320 ) 2000 sin 20.556 / 1 = 20.556 = 702.2 O O tan- (0 / 320 ) 2000 sin 0 / 0 = 0 = undefined -1 134 tan-1 ( 134 / 320 ) 2000 sin 22.720 / 1 = 22.72 = 772.456 -2 278 tan" ( 278 / 320 ) 2000 sin 41 / 2 = 41 = 656 Xavg ( 615.66 + 702.2 + 772.456 + 656 ) / 4 = 686 Alavg (772.456 - 615.66 ) / 2 = 78.4Data Table 1. d (nm) = L= Order, Location Angular location n (mm) (degrees) (nm) +2 +1 O 0.0 avg avgACTIVITY 1 Exploring Laser Diffraction 6.

Holding the diffraction 9. Starting from the center of the central dot, grating by its stand, slowly move the measure the distance between the central diffraction grating away from the screen until dot and the center of each of the other dots the interference pattern on the screen is as on the screen.

Use the formula for the interference peaks below to calculate the laser's wavelength for 1. The location of each bright dot can be used each dot. to calculate its angular location by noting that the geometry of the beam is a right triangle 1 = (d sin On) with an equation below. Calculate the angular 4. Calculate the average of the individual location of each dot. Record the results in calculated values for the laser wavelength to Data Table 1. get ave. Record the average in Data Table 1. tan On = Xn/L 5. Estimate the uncertainty of your value of the or wavelength, Adave, by calculating half the On = arctan(X,/L) difference between the largest and smallest value of the wavelength using the equation 2. The slit spacing, d, is not usually given on the below. Record the result in Data Table 1. diffraction grating itself. Diffraction gratings are typically characterized by line density, Alavg = (max - Amin) which is the reciprocal of d. Calculate the slit spacing, d, then convert the units from mm to Disposal and Cleanup nm using the conversion below.
