What are the similarities and differences of light and sound waves?

Light and sound are both waves. The propagation, or distribution of sound, is actually very similar to light, just a whole lot slower. The waves of sound or light both reflect, refract, and attenuate depending on their environment.

For example, you may see that you left a light on in a room from down the hall although you cannot see the actual light bulb. This is reflection. Or if you are outside at night and see a street lamp from far away, it is dimmer than if you are standing right underneath it. This is attenuation.

Achieving usable, uniform light can be challenging in large spaces. There can be issues with shadows, bright spots, and overall distribution of light depending on the room and environment including wall finish, ceiling height, and a lot more. The same is true with audio; however, it is exacerbated by the speed at which the wave travels. Light travels about 900,000 times faster than sound at nearly 300 million meters per second vs sound at 340 m/s or 768 MPH.

A poor audio environment (or system) will manifest sound waves as echoes, muddiness, and overall unintelligible sound. Because sound travels so much slower than light, there is an additional issue with timing. For example, any delayed sound that is heard more than 15 milliseconds after the initial sound will be interpreted as an echo or doubling of sound. You can imagine how a reflective room will continue to reflect this sound over and over again, resulting in extreme intelligibility issues. A properly treated room minimizes reflections, while a properly designed playback system takes care of issues with the uniformity of sound, the same way that many lights in a large room is better than one light.

There are additional issues with interference where an improperly placed speaker can actually cancel out frequencies that a nearby speaker is producing. This is heard as a void where certain frequencies simply cannot be heard. With light this is typically seen as a rainbow such as what you may see on soap film or a compact disc.

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

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Here are some differences: Sound can only travel through a medium (substance) while light can travel through empty space

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.

elly's long hair:

a. if the salon only takes cash, then this isn't the problem. it doesn't matter how much she has in her checking account.   she can't get a haircut until she has the cash.

b. if she has overdraft protection, then there's no problem.   she can go ahead and write a check that her account can't cover, then sometime later, pay the bank some outrageous usury for loaning her a few bucks for a few days, but with beautiful hair.

c. if elly has some principles, and doesn't want to write a bad check, then now she has a problem.   her desire for the new hairstyle is in conflict with her honesty and integrity.

d.   if the bank will not process a check she writes, then even if she had a million $$ in her account, she couldn't use any of it.   the amount she has in her account is not the problem.   and if i may suggest, she might as well close her checking account, and put the money where it'll work for her.   it's not doing her a bit of good in a checking account, since she can't write any checks.

justin can't pay the full balance:

a. he can't even handle the credit limit he has now.   under no circumstances should he ask for a higher limit.

b.   he can ask for the grace period to be extended.   but that's no solution, the bank will almost certainly refuse anyway, and there are much better options.   he knew the rules of his credit card when he started using it.

c.   he definitely should pay the interest on the balance, plus as much of the balance as he can cover at the same time.

d.   he definitely should pay the minimum otherwise they could shut down his card.   he should also pay as much more as he possibly can.   he should also remember the awkward situation he's in, stop buying stuff on credit that he can't afford, and avoid adding any more debt.

i'd say that justin's best best option isn't on this list of choices.   what he has to do:   pay as much as he can at least the minimum payment plus as much more as he can and then avoid adding more debt.
