Light from an argon laser strikes a diffraction grating that has 7,735 grooves per centimeter. The central and first-order principal maxima are separated by 0.488 m on a wall 1.73 m from the grating. Determine the wavelength of the laser light.

wavelength of the laser light is 351nm

Explanation:

The split seperation is

d = 0.01 / 7735

= 1293nm

The angle of the first order maxima

θ = tan⁻¹ (0.488/1.73)

= 15.75°

we have,

≅ 351nm

wavelength of the laser light is 351nm

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
