以下研究方法，与“声波传递能量实验中，通过蜡烛火焰的变化情况来判断声音是否可以传递能量”的研究方法相同的是（　　） A．探究平面镜成像的特点时，用半透明茶色玻璃板来代替平面镜 B．研究光的直线传播时，引入光线来形象的描述光的传播及方向 C．研究音叉振动时，通过乒乓球弹开的远近反映出音叉振幅大小 D．研究声音传播时，抽出玻璃罩中的空气铃声逐渐变小，推测真空不能传声

Solution

Analyze the given options to determine which one is methodologically similar to the experiment involving sound waves and candle flames

Option A involves substitution in an experiment, which is not directly related to energy transfer

Option B describes a visualization technique for light propagation, not an energy transfer experiment

Option C involves observing the effect of vibration amplitude on a physical object, which is similar to observing the effect of sound energy on a candle flame

Option D involves observing the effect of removing air on sound propagation, which is a different concept (sound propagation in different media) than energy transfer

Key Concept

Dynamics deals with the study of forces and torques and their effect on motion, including the transfer of energy through different mediums and the effects of energy on physical systems.

Explanation

Option C is methodologically similar to the sound wave experiment because it involves using a physical change (the distance a ping pong ball is displaced) to infer the amount of energy transferred by the vibrating tuning fork, akin to observing the change in a candle flame to infer energy transfer by sound waves.
