Which color star is hottest
White stars are hotter than red and yellow.
Blue stars are the hottest stars of all..
Is water really blue
The water is in fact not colorless; even pure water is not colorless, but has a slight blue tint to it, best seen when looking through a long column of water. … Rather, water blueness comes from the water molecules absorbing the red end of the spectrum of visible light.
Can humans see Violet
Optics. Violet is at one end of the spectrum of visible light, between blue light, which has a longer wavelength, and ultraviolet light, which has a shorter wavelength and is not visible to humans. Violet encompasses light with a wavelength of approximately 380 to 450 nanometers.
What Colour is space
“So even though space may be full of light, none makes its way to your eye unless you are looking at something bright.” So, Gyuk said, “Because most of the universe is empty, outer space looks black.”
Can you see clouds from space
Clouds can be a nuisance when scientists are trying to observe features on Earth’s surface. But at other times, clouds are exactly what they want to see. These images highlight some of the more beautiful and unusual clouds we’ve observed from space in recent years.
Is the sky blue or purple
The sky is blue — physicists tell us — because blue light in the sun’s rays bends more than red light. But this extra bending, or scattering, applies just as much to violet light, so it is reasonable to ask why the sky isn’t purple.
Why is the sky blue and not any other color
The Short Answer: Gases and particles in Earth’s atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
What is the real color of sky
Blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
What is a purple sky
The purple sky is actually known as scattering, and it occurs when heavy rains rid the atmosphere of larger particles that abord most light. What’s left are smaller particles that scatter the light in all directions. The result is an electric sky, filled with purple and pink colors.
Why there is no light in space
In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.
Is the sky really blue yes or no
Our sky is actually purple But the answer to why we see blue skies isn’t a matter of physics; it’s an answer for physiology. … The predominant blue and purple scattered light triggers not only the blue cones in the eye, but also a little of the red and green cones.
Why is the sky blue but space is dark
Since you see blue light from everywhere overhead, the sky looks blue. In space, there is no air. Because there is nothing for the light to bounce off, it just goes straight. None of the light gets scattered, and the “sky” looks dark and black.
