Question

A bell is rungs by striking it once. The vibration builds up in intensity becoming loud enough to hear. The concepts is known a
A) resonance.
B) wave refraction.
C) incremental amplitude.
D) a compresiional disturbance.

Answer 1

Answer: C i.e scattering is the correct answer.

Scattering type of Polarization occurs when light strikes the atoms of a material.

Polarization is the process of transforming unpolarized light into polarized light. There are four methods of polarisation--Transmission, Refraction, Reflaction and Scattering.

Explanation:

Answer 2

The answer is A. resonance. A resonant frequency means a natural frequency which is a part of vibration made by the physical parameters of any vibrating object. A vibrating object will get the resonant frequency from complex excitation and would vibrate.
