CWNA: Certified Wireless Network Administrator v108 — Question 15

An RF signal sometimes bends as it passes through some material other than free space. What is the term that describes this behavior?

Answer options

• A. Refraction
• B. Warping
• C. Scattering
• D. Reflection

Correct answer: A

Explanation

The correct answer is 'Refraction,' which specifically refers to the change in direction of a wave as it passes from one medium to another. 'Warping' is not a recognized term in this context, while 'Scattering' describes the redirection of waves in various directions, and 'Reflection' pertains to waves bouncing off surfaces rather than bending through materials.
