Is blue light or red light hotter?
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.
When light waves strike a blue object what happens to the light waves of all colors?
When light waves strike a blue object, the object absorbs most of the colors in the light spectrum except for blue. Blue light waves are reflected off the object, giving it its blue color.
In the light spectrum are red waves shorter than blue waves?
Red light waves are almost double the length of blue or violet light waves. Wavelength is inversely proportional to frequency; red light has a higher frequency than blue light.
How do you Compare red light and blue light using the term energy?
This is a good question, and one that is of interest to those concerned with the environment. To understand energy in light, we need to understand waves and wavelengths.Consider waves on an ocean - each wave has a high peak and a low trough, and the ocean is an endless cycle of peaks and troughs. If we were to measure the distance from one peak to the next peak, that measurement would describe the length of one wave. This measurement is appropriately called the wavelength. On the ocean, we would likely measure wavelengths in feet or meters.Light travels in waves too, but unlike ocean waves, light waves are so small that we cannot see individual light waves. In fact, light waves are so infinitesimally tiny, we describe light wavelengths in nanometers (a nanometer is one billionth of one meter) or often in Angstroms (1 tenth of a nanometer, or one ten-billionth of one meter).Visible light ranges in wavelength from approximately 4000 Angstroms (blue) to 7000 Angstroms (red). Blue light is therefore carried by waves that are shorter than red light.Ultraviolet light has even shorter waves than blue light (100 to 4000 Angstroms), while at the other end of the spectrum, infrared has even longer waves than red (7000 to 10,000,000 Angstroms).The amount of energy in light is inversely proportional to its wavelength. In other words, as the wavelength of light becomes shorter (more blue), the energy carried by that wave becomes higher. Specifically, the energy calculation for light is:E (hc)/λ,Where h is Planks Constant, C is the speed of light, and λ is the wavelengthWhile we will not concern ourselves with the mathematics here, the following statements help illustrate the relationship between light color and energy:Blue light (4000 Angstroms) has 75% more energy than red light (7000 Angstroms) when both lights are exactly the same brightnessUltraviolet light (1750 Angstroms) has four times more energy than red light of the same brightnessAs an aside, the relationship between light color and energy is what has so many people concerned about the ozone layer. The ozone layer is a very high, very thin layer of ozone (O3), and one interesting property of ozone is that it filters out ultraviolet light. Without the ozone layer, high energy ultraviolet light penetrates the atmosphere, and reaches us on the Earth's surface. Because ultraviolet light carries so much more energy at the same brightness than visible light, it has the potential to cause more damage to our bodies, including cancer.
Do photons of blue light have more or less energy than photons of red light?
Photons of Blue light have more energy than photons of red light. Ultraviolet have even more, x rays yet more, gamma rays still more, and some cosmic rays still a lot more. Infrared have less, and radio waves have less, and other waves have even less.

Do red waves orange waves blue waves or radio waves have a higher rate of energy?
Higher energy is carried by electromagnetic radiation with higher frequency (shorter wavelength). Of the items listed in the question, the one with the highest frequency (shortest wavelength) is blue light.

Red light waves are almost double the length of blue or violet light waves. Wavelength is inversely proportional to frequency; red light has a higher frequency than blue light.

Which puts off more energy red light or blue light?
blue light puts off more energy when looking at the Electromagnetic spectrum as a whole from the right to left (or from highest wavelength and lowest frequency (i.e radio waves) all the way to gamma rays with extremely small wavelengths and high frequencies) the energy increases. so the energy of radio waves is much smaller than gamma rays now to put that to use in the problem of light, we know that red light has a larger wavelength (somewhere around 600-700 nm) and blue light with a smaller wavelength of somewhere around 475 nm thus the frequency (wavelengths per unit time) is larger for blue light using the equation E=((hc)/wavelength) where E is energy, C is the speed of light (3x10^8 meters/second) h= planks constant of 6.626 x 10^-34 joules x seconds we find that plugging in a smaller wavelength gives us a higher energy so blue puts off more energy hope that helps
What bends more light waves with short wavelengths or light waves with long wavelenths?
Light waves with shorter wavelengths bend more compared to light waves with longer wavelengths when passing through a medium due to the phenomenon of dispersion. This is why we see rainbows, where shorter wavelengths (violet/blue) are bent more than longer wavelengths (red) when passing through water droplets.
Explain the differences between the waves that make up bright green light and dim red light?
Waves of bright green light have higher frequency (shorter wavelength) and higher amplitude than waves of dim red light have. For example, if the colors were red and blue, Red light has a wavelength of 750 nm and blue light has a wavelength of 500 nm. Their wavelengths will differ.
What color of light has the greatest amount of energy?
Blue light has the greatest amount of energy among visible light. It has a shorter wavelength and higher frequency compared to other colors, which translates to higher energy per photon.
Does blue light have a greater speed than red light?
Blue light is diffracted more than red. The way I remember is by thinking about the waves being closer together in the blue light and knowing that each wave interacts with the whatever is causing the diffraction (grating or object). More waves in a given area means more interaction which means more diffraction.
Does red light have a longer wavelength then blue because it's the first colour in the rainbow?
Yes, red light has a longer wavelength than blue light. In the visible light spectrum, red light has a longer wavelength and lower frequency compared to blue light. This difference in wavelength is due to how light waves interact with various materials and how they are diffracted within the atmosphere.
