Mechanical waves don't require a medium.

• It depends on the type of mechanical wave.

• True, but only medium mechanical waves need a medium.

• True. Mechanical waves are able to travel through air, water and solids.

• False. Mechanical waves cannot travel through a vacuum.

If a sound wave traveled from a solid to a liquid its speed would __________.

True or false: You can change the speed of a sound wave by increasing the wavelength.

• False. You must decrease the wavelength in order to increase the speed of sound.

• False. Wave speed is determined by frequency, not wavelength.

• False. The speed of sound can only be changed by changing the medium.

• True. If the wavelength is increased, then more waves pass per second and the speed of sound increases.
