How are light energy and sound energy alike and different?

Answer 1

They can both be analyzed as waves, but light is also a particle phenomenon. Sound must have a medium through which to travel; no medium, no sound. Light needs no medium through which to travel. Our experience of both sound and light can change by what is called the Doppler Effect; the frequency of the waves depends on the movement of the source relative to the observer. However, the waves of light themselves are always moving at c (in a vacuum) regardless of the movement of the source relative to the observer. Sound waves, on the other hand, do change speed depending on the relative movements of the source and observer. If the observer is moving through the air at a given velocity, some fraction of that velocity might be added to or subracted from the velocity of the observed sound.

Answer 2

difference is, sound travels in waves and light travels as packets of energy called photons.

Light s faster than sound.

Alike : simply both are energy

ANSWER: They are both the same except for the frequency spectrum sound is at the very low end and light is at the extreme of the hi frequency

Answer 3

Both have:

1)They are both caused by vibrations.

2)Both reflect echoes from walls and light from mirrors.

3)Both can impact energy on an object over a distance. Sound can make something vibrate or put pressure on your eardrum. Light can make something worm or energize the photoreceptors (specialized nerve cells in the retina that are responsible for vision).

Differences:

1) Sound is mechanical energy, light is electromagnetic energy.

Answer 4

Light is electrical energy, and sound is mechanical energy!
