Perspex is cheaper. 100%. Defo. IRL.
perspex is not a kind of glass, it's a clear acrylic resin which is used as a substitute for glass in some applications.

Velocity of Sound was created on 2002-10-08.
perspex is a plastic
the velocity of sound in the air is 300m/s
Write an experiment to find the velocity of sound?
Perspex Island was created in 1991.
Sound velocity is greatest in solids, and the solid with the highest velocity of sound is metallic Beryllium.
As density increases, the velocity of sound increases because there are more particles for the sound wave to travel through. Conversely, if the density decreases, the velocity of sound will also decrease because there are fewer particles for the sound wave to travel through.
Velocity of sound in air is 324m/s.
Perspex is cheaper. 100%. Defo. IRL.
Perspex (PMMA) is not a soft solid.
Speed of sound has no effect on the particle velocity. Call velocity of sound better speed of sound. Call sound velocity better particle velocity. Velocity of sound is not sound velocity.
