What property describes how a material bounces back after being disturbed quizlet?
Elasticity will determine how well the particles in the medium bounce back after being disturbed. Density will determine how fast the sound will travel; sound travels slower in denser mediums. Temperature will also determine how fast sound travels; the lower the temperature, the slower the sound will travel.
How do elasticity density and temperature affect the speed at which sound travels through a medium?
In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium. In air, for example, the speed of sound increases with an increase in temperature. At 32 °F.
What is the material through which a wave travels?
Medium
Medium – a material through which a wave travels.
How do elastic properties affect wave speed?
Sound waves are made up of kinetic energy. It takes more energy to make large molecules vibrate than it does to make smaller molecules vibrate. Thus, sound will travel at a slower rate in the more dense object if they have the same elastic properties.
What is the turning back of the wave as it hits the barrier?
The bouncing back of a wave after it strikes a barrier is called refraction. reflection is the bending of a wave as it enters a new medium at an angle other than 90 degrees.
How the elastic properties of materials affect the speed of sound?
Materials with higher elastic properties return to their normal shape faster, making it easier for sound to travel through them. That’s why sound travels much faster through lead, for example, than rubber, which has very low elastic properties.
How does density affect elasticity?
A substance that is more dense per volume has more mass per volume. Usually, larger molecules have more mass. If a material is more dense because its molecules are larger, it will transmit sound slower. The elastic properties usually have a larger effect that the density so it is important to both material properties.
When a wave strikes an object and bounces of?
Reflection is where a wave strikes an object and bounces off.
