What happens to absorbed light?
Absorbed light is converted into other forms of energy, such as heat or chemical energy. In photosynthesis, absorbed light is used to convert carbon dioxide and water into glucose and oxygen. In solar panels, absorbed light is converted into electricity.
When light bounces is it absorbed?
When light bounces off a surface, it is not absorbed by the surface unless the material is specifically designed to absorb light, such as in solar panels. Instead, the light reflects off the surface, which allows us to see objects and colors.
How much solar energy is absorbed and how much is reflected from the earth's surface?
At the earth's surface about 51% of incoming solar radiation is absorbed, and 4% is reflected back into space.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
What happens to the absorbed light energy when a light wave is absorbed by an object?
When a light wave is absorbed by an object, the absorbed light energy is converted into heat or other forms of energy within the object.
What energy changes take place in a solar cooker?
In a solar cooker, solar energy (light and heat) is absorbed by the reflective surface and converted to heat energy. This heat energy is then transferred to the food in the cooker, causing it to cook or heat up.

What is the starting and finishing energy for a solar cell calculator?
The starting energy for a solar cell calculator refers to the amount of solar energy being absorbed by the cell. The finishing energy is the electrical energy output generated by the solar cell after converting the absorbed sunlight into electricity.
What is the amount of solar energy that is absorbed in gasses clouds and ozone?
The solar energy that is absorbed in gasses clouds and ozone is little. The UV spectrum is absorbed.
How is chemical energy transformed into thermal energy in a solar oven?
In a solar oven, the sunlight is absorbed by a dark surface inside the oven. This absorbed light energy is then transformed into thermal (heat) energy, causing the interior of the oven to heat up. The dark interior of the oven helps to efficiently convert the light energy into thermal energy.

How are light absorption and temperature related?
Light absorption can lead to an increase in temperature when light energy is absorbed by an object and converted into heat. The absorbed light energy raises the kinetic energy of the object's molecules, causing them to move faster and generating heat. This relationship is commonly observed in phenomena like the greenhouse effect and solar heating.
What happens to most solar radiation when it reaches the surface of Earth what happens?
Most of the solar radiation is absorbed when it reaches the surface of the earth. Some of the solar radiation is also absorbed in the atmosphere.
What energy transformation occurs in solar panels?
In a silicon solar cell, light energy (a photon of energy >~ 1.1eV) is absorbed in silicon and the energy absorbed excites an electron-hole pair so charge particles are formed. If there is an electric field, the charge particles will separate and an electric current occurs.
The solar radiation least absorbed by the layers of the atmosphere before reaching Earth is?
Ultraviolet radiation is the solar radiation least absorbed by the layers of the atmosphere before reaching Earth. This is due to the ozone layer, which helps to absorb and block a significant portion of the incoming ultraviolet radiation.
