If The Grating Is Assumed To Be 600 Mesh I 600 Bars Per Inch Calculate The Angle

2. If the grating is assumed to be 600 mesh (i.e. 600 bars per inch), calculate the angle (2q) for the position of the first diffraction peak. Also calculate the distance to the spot on the screen in inches and compare this calculation to the measurements made in class (provided in question 1).

 The relevant parameters for the unknown grating are (measured in class) required for the calculation: Sample to detector distance (i.e. laser to screen)= 947.4 cm Wavelength of laser light: 632.8 nm or 632.8 x10-7 cm (helium-neon laser)
