Whatever the colors are, the brighter light results from the beam of more photons.

But each individual blue photon carries more energy than each individual red photon.

Why is current is weaker in dim light than in bright light?

In dim light, the number of photons reaching the solar panel is lower, which results in a lower generation of electron-hole pairs and therefore less current being produced. Bright light provides more photons, resulting in a higher generation of electron-hole pairs and a stronger current flow.


Why might blue light cause emission of electrons from metal while red light does not?

Blue light will eject electrons from a photosensitive surface because blue light has a high frequency. The high photon frequency of the blue light means it has more energy because the frequency is directly linked to the energy of the photons. Red light would not eject electrons because it has a low frequency.


Why are the hottest stars blue and the coldest stars red?

Blue photons are higher-energy than red photons. The equations governing the emission of light based solely on temperature state that an object giving off primarily blue light is hotter than one giving off primarily red light.


What flame color emits more photons?

The flame color that emits more photons is typically blue. Blue flames have a higher temperature and more complete combustion, resulting in a greater number of high-energy photons being released. In contrast, yellow or orange flames, which are cooler and often result from incomplete combustion, emit fewer photons overall. Thus, the intensity and energy of the blue flame contribute to its increased photon emission.


Why are x- rays more penetrating than visible light waves?

Higher frequency photons have more energy than lower frequency photons.

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.


Could you emit the same amount of light energy per second which must emit more photons per second a source of red light or a source of blue light?

A source of blue light would need to emit more photons per second to produce the same amount of energy as a source of red light. This is because blue light has higher energy photons, so fewer photons are needed to achieve the same total energy output as red light, which has lower energy photons.


Is the number of photons in one j of red light 650 nm greater than equal to or less than the number of photons in one j of blue light?

The number of photons in one joule of light is inversely proportional to their wavelength. Since red light at 650 nm has a longer wavelength than blue light, which typically has a shorter wavelength (around 450 nm), there will be more photons in one joule of red light than in one joule of blue light. Therefore, the number of photons in one joule of red light is greater than the number of photons in one joule of blue 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

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.


Is there more photons in brighter light?

Yes, brighter light typically means more photons are present because brighter light has a higher intensity, which is measured by the number of photons hitting a given area over time. So, in a brighter light source, there are indeed more photons emitted.


Who discovered that blue light photons have more energy than red light photons?

Planck in his formula E = hf.This was measured by experimenters long before Planck. Einstein's paper on the photoelectric effect explained the observations, Planck later quantified it. Not sure who did the first experiments that discovered the effect.


If blue photons have higher energy than green photons why does green light carry the most energy?

It isn't necessarily hotter. A SINGLE PHOTON (light particle) has higher energy if it is blue than if it is red. But for a beam of light, the temperature also depends on the amount of photons (which basically corresponds to the intensity of the light). The object from which the light originates may be very hot, in which case the light is blue. If the object is not so hot (ha, you'd burn your hand in a second) the light emitted would be red. So the color of the light gives you information about the hotness of the source.


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.


Will bright blue light eject more electrons than dim light of the same frequency?

Yes, bright blue light will eject more electrons than dim light of the same frequency because the intensity of the light directly affects the number of electrons ejected in the photoelectric effect. Higher intensity light will provide more energy to the electrons, leading to more ejections.


How can you make a bright blue fondont a light blue?

You can add more blue food coloring or edible blue dye and knead the dough to mix it very well.
