Which object listed is likely to refract a RADAR beam?

• A. Wood
• B. Plastic
• C. Metal
• D. Concrete

Answer: (B)

When considering which material is likely to refract a RADAR beam, plastic stands out as the correct choice. Refraction occurs when a wave, such as a RADAR beam, passes through a medium and changes speed, subsequently altering its direction. Plastic has a lower density and varying dielectric properties compared to the other materials listed, which enables it to bend and alter the path of the RADAR signal more effectively. In contrast, wood, metal, and concrete typically have denser structures and higher conductivity. These properties contribute to their ability to reflect RADAR waves rather than refract them. In the case of metal, it can reflect nearly all incoming RADAR signals, preventing any significant refraction. Wood and concrete, while not as conductive as metal, also lean more towards reflecting rather than refracting the RADAR beams due to their denser compositions. Therefore, plastic is the most likely to interact with RADAR signals through refraction.
