What is the temperature of blue light?
Blue light itself does not have a temperature because it is a form of electromagnetic radiation, not a physical object. Temperature is a property of matter, such as a light bulb or a star, that emits blue light.
Which is hot a blue star or a red star and why?
All stars are hot. Blue stars are the hottest. The hotter a star is, the shorter the wavelength of light it emits. Blue light has a shorter wavelengths than most other colors.
Does the sun produce blue light?
Yes. The sun produces light across the entire visible spectrum. Its just that the yellow is most apparent. If the sun didn't produce blue light we wouldn't be able to see the color blue by sunlight..
When a star or galaxy moves quickly toward an observer the light it emits will appear?
It will be "blue-shifted". That is, the wavelength of the light will appear to be shorter and so more blue.
Does moon in the sky emits light?
No, it reflects the light from the sun onto the Earth.
What color emission does sulfur have?
Sulfur emits a pale blue light when burned, producing a blue flame.
What is a 6500K fluorescent bulb?
It's a bulb with more blue light in it, to better match the light that natural sunlight emits.

Does a coloured light bulb actually produce light of the same colour spectrum?
There are two types of colored bulbs. Some are just regular light bulbs with a semi-transparent color coating. A blue light bulb, for instance, will transmit blue light, absorbing out red. It will transmit smaller amounts of different colored light, but to your eye the light coming from the bulb is blue.Others actually emit light a a certain color, such as a yellow street light which is a sodium-vapor lamp. Overall the color you see is the color that is being emitted or transmitted.
Does the sun produce blue light?
Yes. The sun produces light across the entire visible spectrum. Its just that the yellow is most apparent. If the sun didn't produce blue light we wouldn't be able to see the color blue by sunlight..
Does a star hold light?
No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.No, it only emits light. The heat gets radiated away as light.
What colour comes through when a red light passes through a blue filter?
Nothing comes through. A red light emits no blue light, and a blue filter allows only blue light to pass ... that's why when you look at it, you say to yourself "Hey! That filter looks blue. I'll call it a 'blue filter'."
What does a white light bulb emit?
A white light bulb emits a combination of all visible wavelengths of light, which is perceived by our eyes as white light. This combination includes red, blue, and green wavelengths of light.
Is a blue light radioactive?
If you mean radioactive as in atomic or nuclear, not necessarily. Light is radiation, regardless of its color, but not usually radioactive in and of itself. Atomic or nuclear radiation has no color.However, by the strictest definition, anything that emits radiation of any kind, such as a blue light bulb emitting blue light (which is radiation), could be considered radioactive.
Is a type of chemical when exposed to radiation emits visible light?
is a type of chemical when exposed to radiation emits visible light.
