3 cards from this section. Quick, good the night before a test.
What is the formula for wave speed?
Think about how frequency and wavelength relate to wave movement.
In which medium does sound travel fastest?
Consider how closely packed the particles are in a medium.
What formula do we use to calculate the speed of a wave?
Remember the correct order of the variables.
Is sound faster in air than in water?
Think about how particles are arranged in different states of matter.
Suppose a sonar device sends out a sound wave with a frequency of 30 kHz in water. Calculate the wavelength if the speed of sound in water is 1482 m/s.
Don’t forget to convert units properly!
An experiment shows sound at room temperature (20°C) traveling at 343 m/s. What is the change in speed of sound at 50°C?
Remember the formula for sound speed found in air.
