Study Notes
Diffraction
- The term "diffraction" was coined by Italian scientist Francesco Maria Grimaldi in 1660, who made accurate observations of the phenomenon.
- In classical physics, diffraction is described as the bending of waves around corners or through small openings, resulting in the spreading of waves beyond their original path.
- The characteristic bending pattern of diffraction is most pronounced when the wavelength of the wave is comparable to the size of the obstacle or aperture.
- The diffraction phenomenon in classical physics is described by Fermat's principle, which states that the path taken by a wave between two points is the path that requires the least time.
- The interference or bending of waves around the corners of an obstacle or through an aperture is called diffraction.
