Light and also sound are both waves. The propagation, or distribution of sound, is actually very comparable to light, simply a totality lot slower. The tide of sound or irradiate both reflect, refract, and also attenuate depending on their environment.

You are watching: How are sound energy and light energy similar

For example, you might see the you left a irradiate on in a room from under the hall although girlfriend cannot watch the actual light bulb. This is reflection. Or if you are outside at night and also see a street desk lamp from much away, the is dimmer than if you room standing appropriate underneath it. This is attenuation.

Achieving usable, uniform light have the right to be an overwhelming in big spaces. There have the right to be issues with shadows, bright spots, and overall distribution of light depending upon the room and also environment including wall finish, ceiling height, and a lot more. The very same is true v audio; however, that is exacerbated by the speed at which the tide travels. Irradiate 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 negative audio environment (or system) will certainly manifest sound waves as echoes, muddiness, and also overall i can not understand sound. Since sound travel so much slower than light, there is second issue with timing. For example, any type of delayed sound the is heard an ext than 15 millisecond after the early stage sound will certainly be taken as an echo or doubling of sound. You can imagine exactly how a reflective room will proceed to reflect this sound over and over again, resulting in extreme intelligibility issues. A appropriately treated room minimizes reflections, when a effectively designed playback mechanism takes treatment of issues with the uniformity of sound, the same method that many lights in a huge room is better than one light.

There are additional issues through interference wherein an improperly placed speaker can actually cancel out frequencies that a adjacent speaker is producing. This is heard as a void where certain frequencies merely cannot it is in heard. V light this is typically seen as a rainbow such together what you might see ~ above soap film or a compact disc.

As you can see based on these properties, a correctly designed audio device whether, that be for playback or sound reinforcement, combined with an environment that can match it, is an essential for an accurate, intelligible, and enjoyable experience.
