Introduction

Diffraction gratings are a crucial tool in physics, used to analyze the properties of light and other forms of electromagnetic radiation. In this problem, we will explore the properties of a diffraction grating illuminated by 500-nm light, which forms a 1st order maxima on the screen at a diffracted angle of 1.146°. We will use this information to find the number of slits per meter for this grating.

The Diffraction Grating Equation

The diffraction grating equation is given by:

dsin(θ) = mλ

where:

d is the distance between the slits (in meters)
θ is the angle of diffraction (in radians)
m is the order of the maxima (in this case, 1)
λ is the wavelength of the light (in meters)

Finding the Distance Between Slits

We are given that the wavelength of the light is 500 nm, which is equivalent to 5 x 10^-7 m. We are also given that the diffracted angle is 1.146°, which is equivalent to 0.02 radians (using the conversion factor 1° = π/180 radians).

We can now plug these values into the diffraction grating equation to find the distance between the slits:

dsin(0.02) = 1(5 x 10^-7)

Solving for d, we get:

d = (5 x 10^-7) / sin(0.02) d ≈ 2.65 x 10^-6 m

Finding the Number of Slits per Meter

Now that we have found the distance between the slits, we can find the number of slits per meter by taking the reciprocal of the distance:

N = 1/d N ≈ 1 / (2.65 x 10^-6) N ≈ 3.77 x 10^5 slits/m

Conclusion

In this problem, we used the diffraction grating equation to find the number of slits per meter for a diffraction grating illuminated by 500-nm light, which forms a 1st order maxima on the screen at a diffracted angle of 1.146°. We found that the distance between the slits is approximately 2.65 x 10^-6 m, and the number of slits per meter is approximately 3.77 x 10^5.
