A bright red light would have more photons compared to a dim blue light. The brightness of a light source is related to the number of photons emitted per unit time, so a brighter light source will have more photons.
Photons reach Earth from the Sun through the process of electromagnetic radiation. These photons are emitted from the Sun's surface as a result of nuclear fusion reactions. The photons travel through the vacuum of space to reach Earth, providing us with light and heat.
The red line corrected for the unequal number of photons emitted across the visible spectrum would likely be a line that is flat or relatively constant across the visible spectrum. This correction aims to account for the differing sensitivity of the human eye to light of different wavelengths, providing a more accurate representation of how light exposure affects biological processes.
Red represent the earth to the Australian Aborigines.
Heat rises from the surface of the earth in the form of infra-red radiation.
Iron glows red when heated because as it absorbs heat, the atoms in the metal vibrate more rapidly and release energy in the form of photons, which are visible as light. This process is called thermal radiation. The specific shade of red comes from the wavelength of the photons being emitted at high temperatures.
UV and infra-red rays are deflected by the earth.
... have roughly double the energy of photons of red light, because their frequency is roughly double the frequency of red-light photons. (That also means that their wavelength is roughly half the wavelength of red-light photons, but this fact doesn't help the current discussion at all.)
Blue Skies, snow capped peaks, sunshine and red earth.
Yes, this is used to make estimates/It is called the Doppler effect
When the wavelength of spectral light emitted from an object increases, it moves towards the red end of the visible light spectrum, also known as the redshift. This indicates that the object is moving away from Earth.
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.
