Questions and Answers

Who coined the word diffraction and recorded accurate observations of the phenomenon in 1660?

Francesco Maria Grimaldi

How is the diffraction phenomenon described in classical physics?

By the Huygens–Fresnel principle that treats each point in a propagating wavefront as a collection of individual spherical wavelets

When is the characteristic bending pattern of diffraction most pronounced?

When a wave from a coherent source encounters a slit/aperture that is comparable in size to its wavelength

What is the diffracting object or aperture effectively considered as in the phenomenon of diffraction?

What causes the most pronounced bending pattern in diffraction?

<p>The addition or interference of different points on the wavefront (or, equivalently, each wavelet) that travel by paths of different lengths to the register</p> Signup and view all the answers
