Question

Light and sound waves both share what characteristic? (2 points)

Answer 1

Answer:

a They both exhibit the Doppler effect.

Explanation:

When source of light or sound and the observer will move relative to each other then due to relative motion of them the frequency of light or sound that is observed by the observer is different from its actual frequency. This phenomenon is known as Doppler's effect.

So here the same characteristic that is exhibit by both is Doppler effect

apart from this

Light is transverse in nature while sound wave is longitudinal

Sound moves faster in water while light moves fastest in air

light do not requires any medium while sound requires medium to travel

so correct answer will be

a They both exhibit the Doppler effect.

Answer 2

Answer:

Answer (A) They both exhibit the Doppler effect.

Explanation:

The Doppler effect, or Doppler shift, describes the changes in frequency of any kind of sound or light wave produced by a moving source with respect to an observer. Waves emitted by an object traveling toward an observer get compressed — prompting a higher frequency — as the source approaches the observer.
