2) explain the two ways by which the pitch of the sound of the generated by a stretched string can be changed

answer in science​

Answer 1

Answer:

Scattering of light is the phenomenon in which light rays get deviated from its straight path on striking an obstacle like dust or gas molecules, water vapours etc. Scattering of light gives rise to many spectacular phenomena such as Tyndall effect and the “red hues of sunrise and sunset”.

Answer 2

Answer:

1) Light scattering by particles is the process by which small particles scatter light causing optical phenomena such as the blue color of the sky, and halos.

2)When the length of the wire is decreased, the frequency increases. ... When the length of the wire is increased, the frequency decreases and the sound produced is less shrill. Using these two ways, the pitch of the sound generated by a stretched wire can be changed.
