When hydrogen fuses into helium a photon of light is produced. The material at the center of the sun is very dense so as the photon travels on its way out of the sun it constantly runs into atoms. It is absorbed and then emitted again. This can happen many millions of times. Some estimates for the time it takes the photon to reach the photosphere range from several thousand years to several million years.
Once the photon leaves the sun it takes about 8 minutes to travel the 145 million km from the sun to the earth.
It then hits the object in question and depending on the what wavelength of the photon is either absorbed or reflected. Lets assume the object is red. If the photon has a wavelength of 650 nm (red light) it will be reflected. If it is 450 nm (blue light) it will be absorbed.
The red light then travels from the object to your eye and hits the retina of your eye. It then hits one if the two types of detectors in your eye, cones for colour and rods for low level light detection. A signal then goes from you eye to your brain through the optic nerve to the visual cortex in the brain.
What else can I help you with?
Does the sun or earth emit light with higher energy?
Only the sun emits radiation in the wavelengths of visible light, which is considerably higher energy than infrared emitted by Earth.
How does light and energy get from the sun to the earth?
It comes on electromagnetic waves.
How does the sun give its energy to the Earth when space has no gravity?
The sun gives its energy to the Earth through electromagnetic radiation, primarily in the form of sunlight. Gravity doesn't play a direct role in the transfer of energy from the sun to the Earth. Space may be a vacuum, but light and energy can still travel through it.
How does energy from the sun travel to the earth?
Most of the energy generated by the Sun travels to Earth as Electromagnetic Radiation. A very tiny amount of energy of the Sun is given off as particles, mostly electrons and protons, flying off into space.Electromagnetic energy is, of course, light. The light energy from the Sun includes the visible spectrum we can see and much more in the infrared part of the spectrum that we can not see and a little in the ultraviolet as well. It all travels at the speed of light from the Sun outwards and a tiny fraction of the Sun's energy strikes the Earth and is absorbed. As a result, the electromagnetic energy is converted to thermal (heat) energy and keeps Earth warm.
Energy leaves the sun as light from a region called?
The energy leaves the sun as light from the region called the photosphere. This is the visible surface of the sun where most of the sunlight we receive on Earth originates.
What did energey from the sun travel to Earth as?
Energy from the sun to Earth travels as electromagnetic energy, or light energy.
What is the primary source of light of all light energy on earth?
it is the sunThe Sun
Does the sun or earth emit light with higher energy?
Only the sun emits radiation in the wavelengths of visible light, which is considerably higher energy than infrared emitted by Earth.
What is the source of light and heat energy for the earth?
The primary source of light and heat energy for Earth is the Sun. The Sun's radiation travels through space and reaches Earth, providing the energy necessary for life to exist on our planet.
How long will it take earth to get to the sun?
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy.
How is the sun a form of light energy?
it gives the earth light and warmth.
What dose earth get from the sun?
Energy in the form of light.
What is earths primary source of light energy?
The Sun is Earth's primary source of light energy. The Sun emits electromagnetic radiation, including visible light, which provides energy for photosynthesis and powers many processes on Earth.
Source of energy heat and light?
The primary sources of heat and light energy on Earth are the sun and geothermal energy. The sun emits light and heat energy through nuclear fusion in its core, which reaches Earth as solar radiation. Geothermal energy comes from the Earth's internal heat, which can be harnessed for heating and electricity generation.
What type of energy is collected from the sun?
The energy collected from the sun is called solar energy. The energy gets to the earth from the sun by radiation that has been affected by the earth's atmosphere.
What is the ultimate energy for all the life on earth?
probably the sun......?
Is a flashlight good model for suns light energy hit earth?
Flashlight is not good model to test sun light hit earth. The light of flashlight is too small energy to compare sun light.
