Bursts of heat and light energy that extend from the surface of the sun are known as solar flares. These explosive releases of energy occur when magnetic energy built up in the solar atmosphere is suddenly released, resulting in intense radiation across the electromagnetic spectrum. Solar flares can impact space weather, affecting satellites and communication systems on Earth. They are often associated with sunspots and other solar activities.

What are the bursts of heat and light energy that extend from the surface of the Sun?
The bursts of heat and light energy extending from the surface of the Sun are known as solar flares. These explosive events occur when magnetic energy that has built up in the solar atmosphere is released, resulting in intense radiation across the electromagnetic spectrum. Solar flares can impact space weather, affecting satellite operations and communication on Earth. They are often associated with sunspots and other solar activity.
Explain Why the sun is major source is energy?
Sun is the source of heat and light energy. It provides energy on earth's surface.
The dense layer of the sun that blocks energy and light is the?
The dense layer of the sun that blocks energy and light is the photosphere. It is the visible surface of the sun and is where the sun's energy is emitted into space as light and heat.
Which type of light energy found in solar radation is most likely to reach the earths surface?
visible light
What surface that absorbs all colors?
A black surface absorbs all colors of light, as it does not reflect any color back to the observer. Instead, it converts the light energy into heat.

Is light mechanical energy?
Light is not mechanical energy but it can be transformed into mechanical energy. Light creates an impact as it hits a surface.
What are some examples of how light energy can be converted into heat energy?
Light energy can be converted into heat energy through processes like absorption, reflection, and refraction. For example, when sunlight hits a dark surface, the surface absorbs the light energy and converts it into heat. Similarly, when light is reflected off a surface, some of the energy is converted into heat. Refraction of light through a medium can also generate heat energy.
What are 3 forms of energy that light can be transformed or converted into when it has been absorbed by a surface?
Light energy can be transformed into thermal energy (heat), chemical energy (in photosynthesis), and electrical energy (in photovoltaic cells) when absorbed by a surface.
Into what kind of energy does light energy change when it meets the surface?
heat
What is the largest source of light energy?
Sun is the largest source of light energy. It provides heat and light on earth's surface.
What happens to most of the energy when earth surface absorbs light?
Most of the light's energy gets converted into heat.
Why does violet light eject electrons from a certain photosensitive surface whereas red light has no effect on that surface?
Violet light has higher energy photons compared to red light. This higher energy allows violet light photons to transfer enough energy to electrons in the photosensitive surface to eject them, a process known as the photoelectric effect. Red light photons do not have enough energy to overcome the work function of the surface and therefore cannot eject electrons.
What energy transformation takes place when a match is struck against the side of the matchbox and bursts into flames?
Friction between the match head and the rough surface of the matchbox causes the match head to heat up, converting mechanical energy into thermal energy. This increase in temperature eventually ignites the match head, producing light and heat energy in the form of a flame.
When light hits an object most of the light is absorbed by what?
When light hits an object, most of the light is absorbed by the surface of the object. The absorbed light energy is then converted into heat, which can lead to the object warming up. The color of the object determines how much of the light is absorbed and how much is reflected.
Where is light absorbed or reflected?
Light can be absorbed or reflected at the surface of an object. When light hits an object, the surface material can absorb some of the light energy, causing it to be converted into other forms of energy like heat. Alternatively, the surface material can reflect the light, bouncing it back in various directions.
What does light produce in the photoelectric effect?
Light produces electrons in the photoelectric effect. When light of sufficient energy (photon energy) shines on a metal surface, it can eject electrons from the surface, creating a flow of current.
