Question 7 (1 point)

Be able to list 6 of the major types of electromagnetic radiation, and for each provide a common use and a common danger. For example, what is UV light and what is its danger?

Question 7 options:

	UV light has a longer wavelength than visible light, and is more energetic. It is associated with an increased risk of skin cancer.
	UV light has a longer wavelength than visible light, and is more energetic. It is associated with an increased risk of heat stroke.
	UV light has a higher frequency than visible light, and is more energetic. As in visible light, it creates no health issues.
	UV light has a higher frequency than visible light, and is more energetic. It is associated with an increased risk of skin cancer.

Question 8 (1 point)

Why is it unlikely that cell phones present a health danger?

Question 8 options:

	Radio waves are short wavelength and therefore high energy energy, and are considered non-ionizing radiation.
	Radio waves are long wavelength and therefore high energy. They are considered non-ionizing radiation
	Radio waves are long wavelength and therefore low energy. They are considered non-ionizing radiation.
	Radio waves are short wavelength and therefore high energy. They are considered ionizing radiation.

Question 9 (1 point)

The pitch of sound depends upon _____ of sound.

Question 9 options:

	both frequency and wavelength.
	the displacement
	neither frequency and wavelength.
	the amplitude

Question 10 (1 point)

What is meant by non-ionizing radiation?

Question 10 options:

	It does not have enough energy to "knock" an electron off an atom, so it would cause cellular mutations.
	It does not have enough energy to "knock" an electron off an atom, so it would rarely cause cellular mutations.
	It cannot penetrate glass.
	It cannot change an ion into a molecule.
