In a single-slit diffraction pattern, where is the first minimum located?

In a single-slit diffraction pattern, where is the first minimum located?

Step 1: Understand that a single-slit diffraction pattern is created when light passes through a narrow slit.
Step 2: Know that the pattern consists of bright and dark areas on a screen.
Step 3: The dark areas are called minima, and the first minimum is the first dark spot you see after the central bright spot.
Step 4: The position of the first minimum is determined by a specific formula.
Step 5: The formula for the angle (θ) where the first minimum occurs is θ = λ/a.
Step 6: In this formula, λ (lambda) represents the wavelength of the light, and 'a' is the width of the slit.
Step 7: To find the first minimum, you need to know the values of λ and a.
