Employees at GetWell research labs are analyzing mechanical waves, which require a medium to pass through, and electromagnetic waves, which travel through space. Jose Gonzalez IV is studying electromagnetic waves and their potential, real-world health and medical applications. He records the lengths of the various waves, noting that radio waves are the longest, while Gamma rays are the shortest. When calculating the frequency of the wave, or the number of wavelengths that occur in a distinct amount of time, Jose notes that there is an inverse relationship between the frequency of a wave and its period, which is the time it takes for a single wave to occur.

Wave type Wave length size Application
Radio Waves Grater than 30cm Aircraft Naviagtion, TV, AM/FM Radio
Infrared Waves 30cm - 1mm Microwave Ovens, Mobile Phones
Visible Light 1mm - 700nm Remote Controls, Toasters, Night Vision
X-Rays 700nm - 400nm Physical Therapy, Light Bulbs, Photography
Ultraviolet Light 400nm - 60 nm Sanitation, Air Purification, Forgery Detection
X-Rays

60nm - \(1 \times 10^{4}\)nm

Medical Examination, Cancer Treatment
Gamma Rays 0.1 nm - \(1 \times 10^{5}\) nm Cancer Treatment, Food Irradiation

Based on the information provided, which types of waves have potential medical applications? Choose all that apply.

 

Explanation

In order to answer this question, you need to look at the “Applications” section of the provided table and select waves that relate to medical research. According to the chart, Visible Light is used in physical therapy, Ultraviolet Light is used in sanitation and air purification, and both X-rays and Gamma Rays are used to treat cancer. Thus, you should select (c), (d), (e), and (f).
