Light and sound are both waves. The propagation, or distribution of sound, is in reality very comparable to light, just a totality lot slower. The waves of sound or light both reflect, refract, and also attenuate depending on their environment.
You are watching: How are sound energy and light energy similar?
For example, you may see that you left a irradiate on in a room from under the room although you cannot watch the actual irradiate bulb. This is reflection. Or if friend are external at night and also see a street lamp from far away, the is dimmer than if you room standing right underneath it. This is attenuation.
Achieving usable, uniform light can be an overwhelming in large spaces. There deserve to be concerns with shadows, shining spots, and also overall circulation of light relying on the room and environment including wall surface finish, ceiling height, and a lot of more. The same is true with audio; however, it is exacerbated by the speed at i beg your pardon the tide travels. Light travels around 900,000 times much faster than sound at almost 300 million meters per 2nd vs sound at 340 m/s or 768 MPH.
A poor audio atmosphere (or system) will certainly manifest sound waves together echoes, muddiness, and overall i can not understand sound. Since sound travels so much slower than light, there is an additional issue with timing. Because that example, any delayed sound the is heard much more than 15 millisecond after the early stage sound will certainly be construed as an echo or doubling of sound. You have the right to imagine exactly how a reflective room will proceed to reflect this sound over and also over again, resulting in too much intelligibility issues. A effectively treated room minimizes reflections, while a correctly designed playback mechanism takes care of worries with the energy of sound, the same means that numerous lights in a large room is much better than one light.
There are extr issues through interference whereby an improperly inserted speaker can actually cancel the end frequencies that a surrounding speaker is producing. This is heard as a void where specific frequencies just cannot it is in heard. With light this is typically seen together a rainbow such as what you might see ~ above soap movie or a compact disc.

As you can see based upon these properties, a appropriately designed audio system whether, it be for playback or sound reinforcement, combined with an atmosphere that can match it, is crucial for an accurate, intelligible, and enjoyable experience.
