Question

Which is not a factor affecting the speed of a sound wave?

density
temperature
elasticity
reflectivity

Answer 1

Reflectivity is not a factor affecting the speed of a sound wave. The speed of sound waves depends on the density, temperature, and elasticity of the medium through which it travels. Reflectivity refers to the ability of a medium to reflect sound waves, which affects the direction and intensity of the sound but not its speed.
