Question

Quizplus · Accepted Answer

Sound shadow is the phenomenon where sound waves are blocked by an object, leading to reduced intensity of the sound on the opposite side of the object. This depends on two factors: the size of the head (or the object causing the shadow) and the frequency of the sound. Lower frequency sounds can diffract or bend around the object, whereas higher frequency sounds are more likely to be blocked. The size of the head also plays a role in determining the size of the sound shadow. Therefore, option B is the correct choice as it mentions the two relevant factors.
