blue and green light
What else can I help you with?
What wavelengths does carotene absorb?
Carotenoids reflect yellow-orange light and absorb blue-green light.
Why are carotenoids orange?
Carotenoids are orange because they absorb light in the blue-green part of the spectrum and reflect or transmit the red-orange wavelengths, giving them their distinctive color. This absorption and reflection of specific wavelengths of light contribute to their orange hue.
What wavelength of light does chlorophyll a reflect?
There are 2 different types of chlorophyll. Chlorophyll "a" absorbs light in the violet and red regions of the visible spectrum while chlorophyll "b" absorbs light in the blue and red regions of the visible spectrum.
What color does an object appear to be if it absorbs all the colors of light?
If an object absorbs all the colors of light, it will appear to be black. It is the reflected part of the spectrum that gives an object its color.
Which region of the visible spectrum is not absorbed well by chlorophyll?
Green light is not absorbed well by chlorophyll, which is why plants appear green to our eyes. This is because chlorophyll absorbs more efficiently in the blue and red regions of the visible spectrum.
How do heat transfers by radiation?
Heat transfer by radiation occurs in the infra-red part of the electromagnetic wave spectrum, because matter emits and absorbs radiation with that range of frequencies.
Why in Light refraction do black objects remain black?
Light "refraction" is the bending of light as it passes through a transmitting medium, Refraction has nothing to do with black objects. A black object reflects no parts of the visible part of the spectrum, it absorbs them all. A white object reflects all parts of the visible spectrum. A red object reflects the red part of the spectrum, absorbing the rest.
Why does an object appear yellow?
An object appears yellow because it reflects wavelengths of light in the yellow part of the visible spectrum and absorbs other wavelengths. Our eyes perceive this reflected light as the color yellow.
Where in the electromagnetic spectrum are pulsars best observed?
Pulsars are best observed in the radio part of the electromagnetic spectrum. This is because their strong radio emission allows them to be detected and studied using radio telescopes. However, pulsars have also been observed at other frequencies, including X-ray and gamma-ray wavelengths.
Which part of the electromagnetic spectrum generally gives us your best views of stars forming in dusty clouds?
Infrared
Is light part of the radio spectrum?
No, light is not part of the radio spectrum. But, both the radio spectrum and light are part of the electromagnetic spectrum. The electromagnetic spectrum is a range of frequencies from very low to very high. Light frequencies are higher than radio frequencies but both are the same kind of thing.
What is the part of the electromagnetic spectrum called?
We call that the visible or optical spectrum.
