Red light is hotter than blue light. This is because red light has a longer wavelength and lower frequency compared to blue light, meaning it carries less energy. Temperature is related to the average kinetic energy of particles in a substance, and red light has less energy to transfer compared to blue light.

How color of light is related with surface temperature?
The color of light emitted by an object is related to its surface temperature through a principle called blackbody radiation. As an object gets hotter, it emits shorter wavelengths of light, shifting from red to orange to white and eventually blue as the temperature increases. This relationship is described by Wien's displacement law.
Which book, the red one or the blue one, sitting on the table is considered hotter?
The red book on the table is considered hotter.
Which color of light is produced by mixing red light and blue light?
Mixing red light and blue light produces magenta light.
What color does blue and red make in light?
Blue and red light mix to create magenta light.
Does blue or red have a higher frequency?
Blue light has a higher frequency than red light. When we see different colors, we are actually perceiving different wavelengths of light - blue light has a shorter wavelength and higher frequency than red light.
Does blue fire mean it's the hottest or coldest or electric?
Blue light is of a higher energy than red light. That means that the fire with the blue light is hotter, as the fire must generally be hotter to generate the blue light. For example, in a gas flame, the blue, which is hottest, is in the middle, and any yellow, orange or red is around the outside.
What is the difference between red blue and white stars?
Red stars are cooler and emit more red light, blue stars are hotter and emit more blue light, while white stars fall in between and emit a broader spectrum of light. This color variation is due to differences in the stars' temperatures and compositions.
What star is hotter a star giving off red light or blue light?
That question is a little tricky. What is certain is that if the light is coming from a hot object like a glowing heater element, yellow light indicates that the element is hotter. It is also true that a single photon of yellow light carries more energy than a single photon of red light and is "hotter" in that sense. So in general, yellow light is hotter, but if you are simply talking about narrowband filtered light from a single source, a human will not ordinarily be able to sense the difference, and which color is more intense will depend on the spectrum of the light source.
Is a blue star hotter than a red giant?
blue stars are hotter
Which is hotter red stars or whitish - blue stars?
White Dwarves and Blue giants are both hotter than Red giant stars.
Is a flame red flame hotter than a yellow flame?
Yes, typically a red flame is hotter than a yellow flame. The color of a flame is determined by the temperature of the burning material. In general, hotter flames appear bluer or white, while cooler flames tend to appear yellow or red.
Is white hot hotter than red hot?
Yes. Red comes from the lowest energy range of and blue from the highest. LMAO So when an object gets hot enough to glow it produces red light first. As the object gets hotter it begins to emit yellow, green, then blue light. But it doesn't stop producing the red light either. So when the object is very hot it is producing red, yellow, green, and blue light. Since white light is all the colors combined, the object looks white.
Which star is hotter a red star or a blue star?
a blue star is hotter then a red star because it is younger and thus has more energy. a good example of this is when you look at a flame on a lighter you see blue light at the bottom because blue is hottest and closest to the heat source whereas the red-orange flame at the top is farther away from the heat source and thus is not as hot as the blue.
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.
Which book, the red one or the blue one, sitting on the table is considered hotter?
The red book on the table is considered hotter.
True or false Red stars are hotter than whittish- blue stars?
False. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
