In a single-slit diffraction pattern, what is the angle for the first minimum?

In a single-slit diffraction pattern, what is the angle for the first minimum?

Step 1: Understand that in single-slit diffraction, light passes through a narrow slit and creates a pattern on a screen.
Step 2: Know that the first minimum in the diffraction pattern occurs at a specific angle.
Step 3: The formula to find this angle is sin(θ) = λ/a, where λ is the wavelength of the light and a is the width of the slit.
Step 4: To find the angle θ, you need to rearrange the formula to find sin(θ).
Step 5: Calculate sin(θ) by dividing the wavelength (λ) by the slit width (a).
Step 6: Use the inverse sine function (arcsin) to find the angle θ from sin(θ).
