The Formula Explained
First Minima Position: \( y = \frac{m \cdot \lambda \cdot L}{w} \)
Where \( m \) is the order of the minima (1 for first, 2 for second, etc.), \( \lambda \) is the wavelength, \( L \) is the distance to the screen, and \( w \) is the slit width.
Glossary of Variables
- Wavelength (\(\lambda\)): The distance between successive crests of a wave, in nanometers.
- Slit Width (w): The width of the slit through which light passes, in millimeters.
- Distance to Screen (L): The distance from the slit to the screen where the pattern is observed, in meters.
How It Works: A Step-by-Step Example
Consider a light with a wavelength of 600 nm passing through a slit of width 0.5 mm, with a screen placed 2 meters away. Using the formula, the position of the first minima is calculated as:
\( y = \frac{1 \cdot 600 \times 10^{-9} \cdot 2}{0.5 \times 10^{-3}} = 0.0024 \) meters.
Frequently Asked Questions (FAQ)
What is single-slit diffraction?
Single-slit diffraction occurs when light passes through a narrow slit and spreads out to form a pattern of light and dark bands.
How do I use the diffraction calculator?
Enter the wavelength of light, slit width, and distance to screen to calculate the diffraction pattern.
What is the significance of the diffraction pattern?
The diffraction pattern helps in understanding the wave nature of light and is crucial in various optical applications.
