frequency,wavelength,amplitude,sound pressure,sound intensity,speed of sound,and direction
The fastest is 18x, but lower speed usually make better quality copies, special for movies and delicate data.
The four elements of voice are pitch (frequency of sound), volume (loudness or softness of sound), tone (quality of sound), and pace (speed of speaking).
The speed of sound in a solid is faster than the speed of sound in air.
The speed of sound in steel is faster than the speed of sound in air.
DVD outputs at a higher bitrate, which would equate to a better picture quality at the same spindle speed.
Quality/Accuracy over speed!! errors can cost the company money...
The waves compress which causes a lower tonal quality.
No, the speed of sound is faster in solids.
