The sun's radiation reaches us in the form of electromagnetic radiation. This type of radiation covers a wide spectrum (that is a wide range of frequencies), but those from the sun are mainly infra-red, visible, and ultra-violet. We and other animals have evolved to use the visible range for sight, the infra-red (that is lower frequency than red) causes warmth in objects that absorb it, and ultra-violet is at a higher frequency than visible light and causes sun burn if you get too much of it. All these frequencies travel at the 'speed of light' which is 300,000 kilometers/sec, and travel best in a vacuum.

What is the cause of photosensitivity?
In animals the main cause of photosensitivity is sunlight. In general "photosensitivity" can be defined as a reaction to any object that is receiving photons, which would include visible light and UV-light.
Which part of the Earth is solid?
Everything in the earth is solid. But earth is not spherical. The earth has large holes that makes up the oceans.
Who was the first women on earth?
the first women on earth was Eve
What does the inside of Earth look like?
1. earth is not dicovered by any one 2. earth is not named after any one
What is the imaginary line that runs through the middle of the earth?
The Equator divides the Earth by the Northern and Southern hemispheres of the Earth, while the Prime Meridian divides the Earth by the East and West Hemispheres.
What is the mass of all photons from the sun striking the Earth in a year?
Mass of photons? Zero, photons have no mass. If you mean energy, that is a different question, ask it.
What does Red photons emitted your the earth represent what?
the mantel
What method of energy from the sun reaches the earth by which method or methods?
in the form of photons
What are particles called that bring heat and light from the center of the sun to earth?
They are called photons.
What causes the biggest problem in detecting infrared photons from an astronomical object from the Earth?
Water vapor
How does the sun affect earths atmosphere?
The Sun sends photons of light particles and they get deflected by Earth's atmosphere
Where the energy transfer happen when earth matieral increases in temperature when put under a lamp?
Energy is transferred from the photons in the light to the molecules of the earth material.
How is solar energy from the Sun transferred to the Earth?
It is transferred by the energy of photons and heat radiation. Convection doesnt work as there is vacuum between sun and earth.
How is solar energy transferred to the sun to the earth?
It is transferred by the energy of photons and heat radiation. Convection doesnt work as there is vacuum between sun and earth.
What is the term for the small packets of energy emitted from light?
Pretty sure it is photons.....
How many times can photons warm the earth with carbon dioxide present?
A single photon can only transfer its energy once. Carbon dioxide prevents heat photons leaving the atmosphere therefore the atmosphere warms.
Why are the photons that emerge from the Sun's surface visible-light photons and infrared-light photons rather than gamma-ray photons?
Photons do not come in different types like infared-photons etc. they are just the wavelength that the photons are at and nuclear fusion just happens to emit photons at a particular wavelength
