Question

Difference between reflection refraction diffraction and scattering

Answer 1

hey there...
here's your answer...
Diffraction is when a wave goes through a small hole and has a flared out geometric shadow of the slit. Diffraction is a characteristic of waves of all types. We can hear around a corner because of the diffraction of sound waves. For instance, if a wall is next to you when you yell, the sound will parallel the wall. The wall may stop, but the voice doesn't; sound will almost turn the corner of the wall. This is diffraction.

Reflection is when waves, whether physical or electromagnetic, bounce from a surface back toward the source. A mirror reflects the image of the observer.

Refraction is when waves, whether physical or electromagnetic, are deflected when the waves go through a substance. The wave generally changes the angle of its general direction.

scattering: light scattering is a form of scattering in which light in the form of propagating energy is scattered. Light scattering can be thought of as the deflection of a ray from a straight path, for example by irregularities in the propagation medium, particles, or in the interface between two media.

Answer 2

✯ Reflection ✯

• ➷ The bouncing back of light is called reflection.

• ➷ It involves only a single medium.

• ➷ After reflection, only change in direction takes place.

✯ Refraction ✯

• ➷ The phenomenon of bending of light is called refraction.

• ➷ It involves two or more than two media.

• ➷ After refraction, changes in direction and velocity take place.
