No. Higher frequency waves simply have a shorter wavelength (that is, the distance from one crest to the next). Lower frequency waves have a longer wavelength. The waves themselves propagate at the same speed (roughly) depending on the medium. For example, sound travels faster in metal or water than it does in air. A good illustration of this would be a line of cars. If each wave crest is a car, a high frequency wave would be one where the cars are each 20 feet apart. A low frequency wave would be one where the cars are 200 feet apart. Both "waves" can be travelling at the same speed (say, 30 miles per hour) HOWEVER! IF the listener is traveling faster RELATIVE to the source of the sound, then the frequency will appear higher. This is called the Doppler Effect. Simply put, if I were stationary next to that line of cars in the previous example, they would pass by at some rate per minute. If I were travelling at 30 mph in the opposite direction along side the line of cars, they would pass by be at TWICE that rate per minute, thus their FREQUENCY would appear to be much higher. But again, the cars (that is the sound waves) individually have not changed speed.

As a objects' temperature increases its' particles move?
Faster.
What happens to molecules as their kinetic energy increases?
They move faster, number of collision increases,also the temperature increases.
Does Temperature increases or decrease when particles are moving faster on average?
As molecules move faster temperature usually goes up.
What happens to the movement molecules when their temperature is raised?
They begin to move faster. The increased temperature increases the energy of the molecule.
Explain how the motion of particles in an object changes when its temperature increases?
When temperature increases the particles of an object gain more heat energy, therefore move faster colliding with each other more.
Do particles in a liquid move faster or slower when the temperature increases?
faster
What do parts in a liquid do?
Move faster as the temperature increases.
As a objects' temperature increases its' particles move?
Faster.
Why do the particles move faster in a vacuum?
Particles do not move faster in a vacuum. Particles move faster when the temperature increases.
When energy is converted to molecules and they move faster does temperature increase or decrease?
As molecules move faster, they cause friction, which increases the temperature of the molecules.
What happens to molecules as their kinetic energy increases?
They move faster, number of collision increases,also the temperature increases.
Does Temperature increases or decrease when particles are moving faster on average?
As molecules move faster temperature usually goes up.
When the temperature increases the particles of the liquid inside a thermometer begin to move faster and what else?
Friction of the particles will increase the temperature. This is how a microwave works.
At higher temperatures what do particels do?
As the temperature of a substance increases, its particles move faster.
Do molecules move more and move apart as temp increases?
As temperature increases, kinetic energy of the molecules increases also, making the molecules move faster and move apart if they are able, as in fluids and gases.
What happens to the movement of molecule when their temperature is raised?
They begin to move faster. The increased temperature increases the energy of the molecule.
What happens to the movement molecules when their temperature is raised?
They begin to move faster. The increased temperature increases the energy of the molecule.
