A student asks a series of questions about a wave. The answer to which question will allow the student to determine whether the wave is electromagnetic or mechanical?

• Does it require a medium in order to travel?

• Does it have a measurable speed?

• Does it have a measurable frequency?

• Can it pass through air and water?

A student reads that radio waves are considered safe, while X-rays are dangerous. The student examines an electromagnetic spectrum shown below. Based on this information, which statement can the student BEST make to explain the difference between radio waves and X-rays?

• The shorter wavelength of X-rays indicates that they are less common.

• The shorter wavelength of X-rays indicates that they have more energy.

• The shorter wavelength of X-rays indicates that they have a higher temperature and can more easily cause burns.

• The shorter wavelength of X-rays indicates that their particles are heavier and can travel farther through matter.
