Sound waves are mechanical waves in which the particles in the medium vibrate in a direction parallel to the direction of energy transport. Identify another name for this type of wave motion.

• transverse waves

• pressure waves

• longitudinal waves

• electromagnetic waves

The graph indicates what about the relationship between wavelength and frequency?

• as wavelength decreases, frequency increases

• as wavelength decreases, frequency decreases

• as wavelength increases, frequency increases

• there is no relationship between wavelength and frequency

If we compare and contrast electromagnetic waves with sound waves, all BUT one statement is true. That is

• sound waves require a medium to travel while electromagnetic waves do not.

• electromagnetic waves can travel through the vacuum of space while sound waves cannot.

• electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere.

• sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.

We spend our lives in visible light without risks to our health. Yet exposure to UV waves in sunlight can cause skin cancer. What is the BEST explanation for this?

• UV waves are longer and carry more energy.

• UV waves are higher frequency and carry more energy.

• UV waves have a lower frequency and carry more energy.

• UV waves travel faster than visible light and have more energy.

Each section of the electromagnetic spectrum has a different amount of energy. Gamma rays have the highest energy and radio waves have the lowest energy. Compare the energy of visible light to the energy of a microwave.

• they have the same amount of energy

• visible light has lower energy than microwaves

• visible light has higher energy than microwaves

• it is impossible to tell the energy of light or microwaves
