How do the frequencies of blue light or red light compare?
The frequency of blue light is roughly double the frequency of red light.
Which frequencies of light is most prone to scattering?
Blue and violet
Is visible light used for photosynthesis?
Yes,visible light is used. Frequencies of blue and red absorbed effectively
What happens when you add blue light to red solid?
You get a dim grey. This is a result of all the minor frequencies of blue light that the red solid does have some reflection to .
How do light colors have higher frequencies and darker colors have lower frequencies?
Darker colors like violet and blue actually have the shortest wavelengths and the highest frequency. If you look at the visible spectrum, the order from highest to lowest would go violet, blue, green, yellow, orange, red.
The color of light is determined by of the light waves.?
The cones in the retina of our eyes are sensitive to certain frequencies of light within the visible light spectrum (ROYGBIV). Light waves with longer wavelengths (within the visible range of frequencies) are perceived to be on the red, orange, yellow side of the spectrum, while higher frequencies/shorter wavelengths of light appear blue or violet.
Why is the sunlight reaching the earth yellowish?
Sunlight is actually light waves of different frequencies. Some of these waves are part of the visible light spectrum (ROYGBIV), and therefore sunlight appears white, a combination of all the frequencies in the visible light spectrum. Light waves with lower frequencies appear more red or orange. Light waves with higher frequencies appear violet or blue. When sunlight shines down through the atmosphere, the particles in the air scatter the light waves of higher frequencies, therefore spreading the waves in different directions in the sky (This is why the sky appears blue). The lower frequency waves reach our eyes mostly undisturbed. Since sunlight has light frequencies dominant in yellow, that's the color we see.
What makes white light?
Light can occur at different frequencies. These frequencies lie on a spectrum, if you want an idea of what the frequencies look like, have a look at a rainbow, with red at the lowest frequency and blue/violet at the highest for visible light. When all of these frequencies are mixed together (like the light created from the "white hot" sun) white light is the result.
Why is colour of copper sulphate blue?
The colour of Copper sulphate is blue because Copper ions absorb light in all frequencies except blue which is reflected instead.
What would a red object look like shone onto a blue light?
Red and blue are at opposite ends of the visible light spectrum, red being of low frequency, and blue being of high frequency. Sunlight contains frequencies across the whole frequency range, which appears white. An object that appears white reflects all frequencies. A red object appears red because it reflects red (low frequency) light, and absorbs all other colours. Blue light contains only high frequencies. If you are in a darkened room, lit only by blue light, white objects will appear blue because they are reflecting the blue light, and no other frequency is available. But a red object absorbs high-frequency (blue) light, and since this is the only light in the room, it does not reflect any light. Objects that do not reflect any light appear black. Some objects appear black even in sunlight, because they absorb all frequencies and do not reflect any. So to answer the question, when you have a red object that is lit only by blue light, it will appear black.
What is the cause of the blue color of ether layer?
Earth's atmosphere is 79% nitrogen, and nitrogen absorbs most light frequencies except blue - it reflects and scatters blue. Hence: Blue sky.
The color of the light is determined by what of the light waves?
The colour of an object is determined by the wavelengths of light it reflects. An object that is purley one wavelength (lets say a specific wavelength in the blue part of the spectrum) would be absorbing all visable wavelengths except that specific blue wavelength.
