Question

Which one of the following terms is used to describe the bending of waves and subsequent spreading around obstacles or the edges of an opening?

A) refractionB) diffractionC) interferenceD) coherenceE) sonoluminescence

Answer 1

B)Diffraction

Step-by-step explanation:

The concept of diffraction in the field of physics is defined as the deflection of a wave when it crosses an opening or hits the edge of an opaque element. Diffraction is a phenomenon that involves all waves: electromagnetic, radio, sound, etc., and it is possible to predict their behavior using different mathematical approaches. There is a method of analysis called the Huygens principle, which allows us to understand diffraction as a wavefront that is seen as a series of emitters capable of redirecting the wave when it oscillates and thus promotes propagation. Although the waves produced by the oscillators are spherical, their interference causes a flat wave that moves in the same direction as the initial one.
