How is temperature related to color? - Physics Stack Exchange The sky appears blue, does that mean its hot? But it isn't right? It's colder I am not sure if I'm able to frame it properly It's a bit confusing to me Is this something like a glowing object vs reflecting object? The sun is white but Earth is blue But sun is hotter than the earth It's the sun radiating light but earth is just scattering it
Why is the sky not purple? - Physics Stack Exchange The net effect is that the red and green cones are stimulated about equally by the light from the sky, while the blue is stimulated more strongly This combination accounts for the pale sky blue colour It may not be a coincidence that our vision is adjusted to see the sky as a pure hue
Why can I never see any stars in the night sky? 2 What color is your sky during the day? If it is deep blue, then you should see lots of stars at night even in a large city If your daytime sky is very light blue though, or worse, pale grey, white, brown, or orange, then you have a problem City light polution will light up this haze at night and make it impossible to see any stars
optics - What makes some laser beams visible and other laser beams . . . 22 What makes the beam of some lasers: visible? such as the ones used in clubs or such as the laser pointers sold at amazon which if pointed to the sky look like a solid visible beam of light crossing the sky (it reminds me of the lightsaber in Star Wars) invisible? such as the ones used in pointers for presentations
optics - Why does the sky look black in pictures taken from the summit . . . In pictures taken from the summit of Mount Everest (such as this one), the colour of the sky is a very dark blue or even black in some pictures I remember from my own experiences of hiking in the Himalayas that the sky appeared to be darker blue as I climbed higher
How can sunlight be white , but pictures of the sun be orange? The main reason why the sun doesn't look white is due to Rayeleigh Scattering means that the blue light from the sun is scattered so it appears to be yellow or even orange when viewed through thicker atmosphere This means that when you take a photograph of the sun (through the necessary filters) from the surface of the earth it will appear yellow or even orange
Why is the blue color of sky darker in high altitude regions? The sky is actually black Check that for yourself at midnight So in the daytime, you are looking at a black sky that is "illuminated" by mostly blue scattered sunlight The higher your altitude, the dimmer is the blue scattered illumination, so you start to see more of the basic black of the sky You can test this on your computer display, by going to the color palette and setting it to full
visible light - Why is the sky never green? It can be blue or orange . . . Can you explain why the colour of the sky passes from blue to orange red skipping altogether the whole range of green frequencies? I have only heard of the legendary 'green, emerald line flash' that appears in particular circumstances Green flashes are enhanced by mirage, which increase refraction is more likely to be seen in stable, clear
visible light - Why is water blue? - Physics Stack Exchange You guessed right, short, which is blue So blue gets scattered with a higher probability into our eyes whichever direction the light comes from, the bluer shorter wavelengths have a higher probability of getting scattered into our eyes, thus we see more blue (and yes, this is in part why the sky is blue)
