What type of diffraction occurs when light passes through a circular aperture?
Correct Answer: Fresnel diffraction
- Step 1: Understand what diffraction is. Diffraction is the bending of light waves when they encounter an obstacle or opening.
- Step 2: Identify the type of opening. In this case, we are looking at a circular aperture, which is a round hole.
- Step 3: Recognize that when light passes through this circular hole, it doesn't just go straight through. Instead, it spreads out.
- Step 4: Learn about Fresnel diffraction. This type of diffraction occurs when light waves pass through an opening and create a specific pattern.
- Step 5: Observe the pattern created. When light diffracts through a circular aperture, it forms concentric rings around the center.
