When the energy of a sound wave is transferred to a particle of a medium and causes it to vibrate and generate hear, the sound wave is
A. reflected
B. refracted
C. absorbed
D. transmitted
I think it's C. check please
I agree, at least part of the sound wave is absorbed. What is left over still can be transmitted or reflected.
To determine the correct answer, let's break down the options and explain how each one relates to the given scenario.
A. Reflected: When a sound wave encounters a boundary between two different mediums, part or all of the wave bounces back. This phenomenon is known as reflection. However, the question does not mention any reflection occurring, so it is unlikely to be the correct answer.
B. Refracted: Refraction is the bending of sound waves as they pass through different mediums with varying densities. Similar to reflection, there is no mention of refraction in the scenario, making it less likely to be the correct answer.
C. Absorbed: Absorption occurs when the energy of a sound wave is taken in by a medium, causing the particles of the medium to vibrate and increase in temperature. This increase in temperature is commonly known as heat. Given that the scenario states that the energy of the sound wave is transferred to a particle of the medium and causes it to vibrate and generate heat, absorption seems to be the most suitable answer.
D. Transmitted: Transmission refers to the sound wave passing through a medium without being reflected, refracted, or absorbed. Although the scenario does mention the sound wave being transferred to a particle of the medium and causing vibration, it also explicitly states that this transferred energy generates heat. Since transmission does not involve the generation of heat, it is unlikely to be the correct answer in this case.
Based on the explanation, it seems that the most appropriate answer is indeed C. absorbed.
Actually, the correct answer is D. transmitted.
When the energy of a sound wave is transferred to a particle of a medium and causes it to vibrate and generate heat, the sound wave is transmitted. Sound waves are mechanical waves that require a medium (such as air, water, or solids) to travel through. As the sound wave travels through the medium, it transfers energy to the particles of the medium, causing them to vibrate and generate heat. So, the correct answer is D. transmitted.
