The property of bending of light around obstacles and spreading of light waves into a geometrical shadow of an obstacle is known as:
- A
Diffraction
- B
Interference
- C
Polarization
- D
Optical rotation
Diffraction, the spreading of waves around obstacles.
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.
So the correct option is A.
The process by which a beam of light or other systems of waves is spread out due to passing through a narrow aperture or across an edge, typically accompanied by interference between the waveforms produced.
Interference is the superimposition of two or more waves having the same frequency emitted by coherent sources such that the amplitude of the resultant wave is equal to the sum of the amplitude of the individual waves.
Polarization is the attribute that wave oscillations have a definite direction relative to the wave's propagation direction. EM waves are transverse waves that may be polarized.
The rotation of the plane of polarization of plane-polarized light by an optically active substance.
