Light of is made up of a finite number of photons, or light quanta. The energy of each photon is proportional to the frequency of the light, and hence inversely proportional to the wavelength of the light. Red light has a longer wavelength than blue light, so the quantum of red light has less energy than the quantum of blue light.
What else can I help you with?
Which has a lower amount of energy red light or blue light?
Red light has a lower amount of energy than blue light. This is because red light has a longer wavelength, which corresponds to lower energy photons, while blue light has a shorter wavelength and higher energy photons.
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.
Does yellow light have more energy than green light?
Yes. Blue light has a lower wavelength than yellow light, which is why it is perceived by out eyes as a different color. Blue light's wavelength is around 450 nanometers and yellow light's wavelength is around 575 nanometers. since the speed of light is constant for all light, and frequency is the speed of light over the wavelength of the light, the larger the wavelength, the lower the frequency. And the lower the frequency, the lower the energy. So the shorter wavelength of light (in this case, blue colored light) has a faster frequency, and therefore more energy.
Why red has a greater wavelength than blue?
Red light has a greater wavelength than blue light because red light has a lower frequency and energy. In the electromagnetic spectrum, longer wavelengths correspond to lower frequencies, while shorter wavelengths correspond to higher frequencies. Therefore, red light, with its longer wavelength, has a lower frequency compared to blue light.
Why does blue light cause a photoelectric effect while red light does not?
Blue light has more energy per photon than red light due to its shorter wavelength. This higher energy allows blue light photons to transfer enough energy to electrons in a material to overcome the work function, leading to the photoelectric effect. Red light, with lower energy photons, does not provide enough energy to eject electrons from the material.
Which has a lower amount of energy red light or blue light?
Red light has a lower amount of energy than blue light. This is because red light has a longer wavelength, which corresponds to lower energy photons, while blue light has a shorter wavelength and higher energy photons.
Why is red light different to blue light?
The red light is lower energy than the blue light.
Is blue light or red light hotter?

How can you tell the energy released based on the colour of the light?
Red light has lower energy photons than blue light. Ultra-violet is even more energetic.
How does blue light compare with ultraviolet light?
The blue light has longer wavelength, lower frequency, andless energy per photon than the ultraviolet light has.The blue light is also visible to the human eyes, whereas theultraviolet light is not.
Why red has a greater wavelength than blue?
Red light has a greater wavelength than blue light because red light has a lower frequency and energy. In the electromagnetic spectrum, longer wavelengths correspond to lower frequencies, while shorter wavelengths correspond to higher frequencies. Therefore, red light, with its longer wavelength, has a lower frequency compared to blue light.

Red light, with lower energy photons, does not provide enough energy to eject electrons from the material.
What color has the lowest energy?
Red, because it has the lowest frequency in visible light
Why does red absorb more light than blue?
Red does as it absorbs photons at blue end of the spectrum( the higher energy) and reflects light at the red end of the spectrum (a lower energy). While the blue light absorbs energy at the red end of the spectrum and reflects blue light
Which has a lower frequency yellow light or blue light?
Blue light has a higher frequency compared to yellow light.
What is the significance of the blue and red light in the experiment?
The blue and red light in the experiment are significant because they represent different wavelengths of light. Blue light has a shorter wavelength and higher energy, while red light has a longer wavelength and lower energy. By using these specific colors of light, researchers can study how different wavelengths affect the outcomes of the experiment.
