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-white star hotter than the sun?
yes
How can you tell if Rigel or Betelgeuse is hotter?
Rigel is hotter by a long way with a temperature of 11,000 Kelvin, whereas Betelgeuse is a cool 3,500 Kelvin
What is the surface temperature of a yellow star?
blue is hotter than red and yellow but yellow is hotter than red.
How far away is a blue star?
The surface temperature (of the main component of this binary star) is about 6300 degrees Celsius.
Can astronomers tell from the elements of a star what uts surface temperature is?
The temperature of a star is determined for it's colour spectrum. The hotter the star the more the spectrum is towards blue where as a cooler star has a spectrum closer to red.
Is the sun or a blue star hotter?
The blue star is hotter
Why is the blue star hotter?
When a star is blue it means it is putting out light mostly in the ultraviolet spectrum which is of a higher energy than infared light, or light in the visible spectrum. This means the star has more energy and heat.
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.
Is a blue star hotter than a red giant?
blue stars are hotter
What is hotter a black star or a white star?
Technically Blue stars are hotter but from your options, white stars are hotter.
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.
What can be said with certainty about a red star and a blue star?
The blue star is hotter than the red star.
What color star is hotter a red star of a blue star?
The red star is the coolest and the blue star is the hottest
Which is hotter a red star or a blue star why?
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.
A white blue star is hotter than a red stra?
The blue star is the hottest.
Is a white-blue star is hotter than a red star?
Yes it is
Why does a star seems to be blue?
Some stars ARE blue - the hotter ones.
