What is diffraction and how it happens?
Diffraction is the spreading out of waves as they pass through an aperture or around objects. It occurs when the size of the aperture or obstacle is of the same order of magnitude as the wavelength of the incident wave. For large apertures the wave passes by or through the obstacle without any significant diffraction.
What is the best definition of diffraction?
Definition of diffraction : a modification which light undergoes especially in passing by the edges of opaque bodies or through narrow openings and in which the rays appear to be deflected also : a similar modification of other waves (such as sound waves) or of moving particles (such as electrons)
Why do things diffract?
Diffraction is the slight bending of light as it passes around the edge of an object. The amount of bending depends on the relative size of the wavelength of light to the size of the opening. Optical effects resulting from diffraction are produced through the interference of light waves.
What is diffraction and example?
The effects of diffraction are often seen in everyday life. The most striking examples of diffraction are those that involve light; for example, the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern seen when looking at a disc.

Who discovered diffraction?
Francesco Maria Grimaldi
Italian scientist Francesco Maria Grimaldi coined the word diffraction and was the first to record accurate observations of the phenomenon in 1660.
What is diffraction sound?
Diffraction. DIFFRACTION. The phenomenon in SOUND PROPAGATION whereby a SOUND WAVE moves around an object whose dimensions are smaller than or about equal to the WAVELENGTH of the sound.
What is diffraction in real-life?
Lights through a shadow of an object is also a real-life example of diffraction. You all have seen when there is bright light behind an object. Our object seems like a shadow and thus this is an example of diffraction. This is the reason behind our object looks black.
What is meant by diffraction in physics?
diffraction, the spreading of waves around obstacles. Diffraction takes place with sound; with electromagnetic radiation, such as light, X-rays, and gamma rays; and with very small moving particles such as atoms, neutrons, and electrons, which show wavelike properties.
