a
visible → infrared → ultraviolet → X-ray → gamma ray → radio → microwave
b
gamma ray → X-ray → ultraviolet → visible → infrared → microwave → radio
c
radio → microwave → infrared → visible → ultraviolet → X-ray → gamma ray
d
microwave → X-ray → gamma ray → ultraviolet → visible → radio → infrared
Question 17 (1 point)
A student is exploring mechanical and electromagnetic waves, compiling a list of questions for her investigation into the properties of each wave type. Which of the following questions would NOT aid her in learning about the properties of both mechanical and electromagnetic waves?

a
What is the wavelength of the wave?
b
What is the wave speed in a vacuum?
c
What is the amplitude of the wave?
d
What is the frequency of the wave?

Answer 1

Question 16: b — gamma ray → X-ray → ultraviolet → visible → infrared → microwave → radio (shortest to longest wavelength).

Question 17: b — "What is the wave speed in a vacuum?" (Mechanical waves require a medium and do not propagate in a vacuum, so this question doesn't apply to them.)
