Question

demonstration of sound and light waves
to demonstrate the properties of sound and light waves, a student shines a light and plays a sound on one side of a piece of metal. the table shows observations about the demonstration
which conclusion does the demonstration support?
light waves transfer more energy because there are no vibrations in the metal, but the sound waves transfer through the metal using vibrations
sound waves transfer more matter because the waves can be detected on the other side of the metal, but the light waves are absorbed by the metal.
both sound and light waves travel without moving particles because the temperature increases, but light waves transfer more energy.
both sound and light waves transfer energy because the temperature increases, but sound waves transfer energy by moving particles

Explanation:

• Waves transfer energy. The increase in temperature of the metal shows that both light and sound waves transfer energy.
• Sound is a mechanical wave. Mechanical waves transfer energy by moving particles (vibrations). Light is an electromagnetic wave and does not need particles to transfer energy.

Answer:

Both sound and light waves transfer energy because the temperature increases, but sound waves transfer energy by moving particles.
