✍️ TYPES OF DISFRACTION

• Fresnel Diffraction
• Fraunhofer Diffraction

Fresnel Diffraction is produced when light from a point source meets an obstacle, the waves are spherical and the pattern observed is a fringed image of the object.

Fraunhofer Diffraction occurs with plane wave-fronts with the object effectively at infinity.

Answer 2

Answer:

There are two types of diffraction=>

1=> Fresnel Diffraction

2=> Fraunhofer Diffraction

Fresnel Diffraction- The source of light and screen are at a certain finite distance from the obstacle/object.

Fraunhofer diffraction - The source of light and screen are at infinite distance from the obstacle/ object.
