• Ground level

• The surface

• Sea level

• The Base of a mountain

What is the speed of sound as it travels through a solid? The speed of sound is _____(use words to spell the unit name) through a solid.

Answer explanation

Remember: When giving this value include a number and unit.

As sound energy moves from water to air, the speed of sound ______, because particles in air are farther apart than in water.

• increases

• remains constant

• fluctuates

• decreases

As sound travels between two(2) different mediums, the frequency remains constant, while the _____ changes.

• Wavelength

• Amplitude

• Period

• Intensity

The reason sound travels at different speeds through different mediums is because of the _____

• Shape of the Particles

• Particle Arrangement

• Size of the Particles

• Temperature

The speed of sound is _____ at sea level than at higher altitudes, because the air particles are more densely packed at sea level.

In and experiment you are Given 200 meters as the distance between 2 people: 1 person holding a pair of blocks and the other person holding a stopwatch. After three(3) trials of listening for the sound of the blocks hitting each other, after you see them, you calculate the average speed of sound in air as 330 meters/second. To calculate what is being investigated in this experiment, use the equation:_____.

In and experiment you are Given 200 meters as the distance between 2 people: 1 person holding a pair of blocks and the other person holding a stopwatch. After three(3) trials of listening for the sound of the blocks hitting each other, after you see them colliding, you calculate the average speed of sound in air as 330 meters/second. What is being investigated in this experiment? The _____ is being investigated in this experiment.
