You get to learn about the basic properties of waves. Check out a few of the factors that affect the speed of waves, and learn about the Doppler effect and the useful property of resonance.
After completing this tutorial, you will be able to complete the following:
Why do mechanical waves move more quickly through solids than through gases?
~ Mechanical waves move more quickly through solids than through gases because mechanical waves propagate with the vibrations of the particles they move through. Since particles in solids are more tightly bound together than the particles in gases, mechanical waves can propagate more quickly through solids.
Through which of the three common states of matter do electromagnetic waves move the fastest and why?
~ Electromagnetic waves move the fastest through gases. Since electromagnetic waves do not require a medium to pass through, they are faster in matter that has fewer particles. The particles in gases are more spread out than the particles in solids or in liquids, so electromagnetic waves move quickly through gases.
Why can't sound travel in a vacuum?
~ Sound cannot travel in a vacuum because mechanical waves, such as sound waves, require a medium to propagate through. Since vacuums contain no matter for the waves to propagate through, sound waves cannot travel through them.
What is the relationship between wavelength and wave speed?
~ Wavelength and wave speed are directly proportional, which means that when the wave speed changes by a certain factor, the wavelength changes by the same factor.
