Final answer:
Ceiling fans with decorative wicker reeds are not as quiet and efficient as those with smooth blades due to increased turbulence caused by the textured surface of the wicker.
Step-by-step explanation:
The question of whether ceiling fans with decorative wicker reeds are as quiet and efficient as those with smooth blades can be answered by considering the aerodynamics involved. Wicker reeds on fan blades can increase turbulence, which typically leads to increased noise and reduced efficiency.
Therefore, option b) No, because wicker reeds increase turbulence, is the correct choice. In contrast, smooth blades are designed to minimize air resistance and noise, which makes them more efficient at moving air quietly.
