Question

what is sonorus property

Answer 1

sonorous property refers to the property of having a ringing sound when beaten.
eg: most of the metals

Answer 2

Meaning of sonorous:

capable of giving a deep, resonant soundmakes a ringing sound when hit

Electron bonding in metals is highly delocalized (due to very low electronegativity). This means that when hit, the electron cloud moves extremely easily - there is very little energy dissipated. This allows the incoming kinetic energy to be easily propagated as a form of disequilibrium (wave).

P.S :- this is not in all metals - it is in sheet metals, and they have to be of relatively low density. High-density metals will not as easily propagate the kinetic energy, due

Metals have high elasticity. Sound requires elasticity for high speed propagation. Generally, in the scales we live in, wavelengths of many "modes" of oscillations are in centimetres thus sounds can easily have audible frequencies.

You can do one experiment to understand what I mean. Take a string and pluck it. Then pull on it and pluck it. Then pull harder and harder as much as you can progressively. You'll start hearing sounds as you make it tighter. This is because making it tighter increases the velocity thus making the frequency in audible range.
