I am just curious. I had someone argue with me that the sky is really clear and the blue during the day is just a reflection from all the ocean water.

It is colorless It gets its different colors like blue or red or purple from the refraction and absorption of wave lengths of visible light,depending on the angle that the light, from the sun, has when it contacts the atmosphere. Rule of thumb. The more vertical the light is the bluer the sky. the more horizontal the light source is the more red the sky becomes.
Nothing to do with reflecting of the ocean-which by the way gets it color by the same method: different medium different colors.

No the blue is caused by the refraction of sun light through the stratosphere and the ocean gets its colour form the reflection of the sky which is why on rainy days it isn't blue

There could properly be many causes for diverse "colorations" of ocean water or clean water. The sky condition can make a huge distinction, as a clean blue sky will be meditated by technique of the water as a darker colour, while a cloudy sky will be meditated as a lighter colour. The intensity of the water adjustments how a lot ordinary is meditated from the sea bottom below. For shallow water, alongside with close to a sea coast, the ordinary meditated from the sand below the water will make the water look lighter (subsequently eco-friendly) than it is going to look if you're in deep water (the position little or no ordinary is meditated from the bottom, ensuing in darkish blue water). ordinary is likewise meditated from the interior of the water also, and the colour of regardless of the truth that is contained in the water (seaweed, soil, suspended sand, etc.) will impact the colour that you spot from the water. The solar attitude impacts the water colour also, as a lot less ordinary is meditated from the exterior, bottom, and interior of the water close to noontime than is meditated for the duration of early morning or evening. The water is likely to look darker round noontime. no longer each and each of the oceans are even an identical colour, or maybe an identical colour in diverse places. quite usually this has to do with what's contained in the water. close to shore, deep currents push up significant quantities of minerals from the seabeds, and microscopic existence florishes. In deeper seas, regardless of the truth that by technique of no ability with out existence, the algeal blooms are literally not modern-day, so there's a clearer view through the water. diverse oceans have diverse mineral content fabric to boot, meaning some handle an rather a lot teal appearence, even as others could look more suitable greyish in colour. i visit inform you from expierience that i have seen each colour of blue that you'll imagine (and some i could in no way imagined) contained in the Pacific ocean, searching on the position i became, the elements, and the time of year.

The particles in the athmosphere filters the lightbeams in such a way that we see only the blue part of the lights color spectre. Pour some milk in a tank of water, and have someone hold a flash light to the glass wall at one end. Go to the opposite side and look at the flash light and milky water. It'll look just like the sun in a blue sky.

Everyone likes to label it as Rayleigh Scattering but still very few explain that term. The Sun emits pure white light. As the sun comes up or sets, the light has more air molecules to travel thru, giving a longer bend to the white light, the reds having a longer frequency, and due to the longer bend of the light from the amount of air, we see reds at sunrise and sunset. AS the Sun climbs higher, it goes thru less air to get to ours eyes. Hence the light is not refracted as much, less bend you might say, blues have a shorter wavelength, so we see blue. Notice on clear cloudless days, the sky is real blue in the middle around noon and appears whitish at the horizon. We are looking at light traveling away from us at the horizon so we see the white light as from the sun. On cloudy or foggy days, less blue because the white light is being filtered by the greyness of the clouds or fog.

In fact, its the other way around.
The sky is truly blue, and the cause is Rayleigh-Jeans scattering. Basically, small particles in the upper atmosphere scatter light, and the angle they scatter it through varies as the 4th power of the light's frequency.
So light coming from the sky - which has to be scattered a lot to reach your eye - is mostly blue. At sunset the reverse applies when you look towards the sun - the light that reaches you has to have been scattered very little so is mostly red.
The sea is blue in part at least because it reflects the blue of the sky.

The sky is blue even in places that are a long way from the ocean. It is nothing to do with the ocean.

I used to know what causes the sky to be blue. All I can tell you now is that it is NOT from the ocean.

Light has seven different colors. (Ever seen a prism). Most of the blue part of the light is filtered through the atmosphere that is why we see the sky blue. Same goes for clouds, clouds bounce all seven colors so we see them white and same for rain clouds they just have a mixture of the colors.

the sky doesn't have any colour - the gas is clear (almost). the blue colour comes from the scattering of sunlight as it passes through the atmosphere. light from teh sun is (roughly speaking) white, but blueish wavelengths are scattered more by our atmosphere so the light hitting the top of our atmosphere and all above us is scattered - blue the most - resulting in teh blue light coming down and red carrying on straight.
this is why to our eyes the sun appears red (red light straight through, blue scattered)
this is why sky is blue the red light passing through above carries on straightish and blue scatterd downwards
this is also why sky at night is not blue - no sun light passing through atmos above us
