Diffraction_Grating_Basics

1. Basics of Diffraction Grating Understanding the Concept

2. What is a Diffraction Grating? • A device with many closely spaced parallel lines (slits or grooves). • It diffracts light into multiple directions, creating patterns. • Acts based on the interference of light waves.

3. Types of Diffraction Gratings 1. Transmission Grating: - Light passes through the slits. 2. Reflection Grating: - Light reflects off the surface with grooves.

4. Basic Principle • Interference of light waves from multiple slits creates patterns. • Patterns depend on wavelength and slit spacing. • Demonstrates the wave nature of light.

5. Applications of Diffraction Gratings • Used in spectroscopy to analyze light. • Helps in measuring wavelengths of light. • Found in optical devices like monochromators and spectrometers.
