What is solar energy?
- A.
Sound energy
- B.
It is the radiant light and heat from the sun
- C.
All of the above
- D.
None of the above
Correct Answer
B. It is the radiant light and heat from the sunExplanation
Solar energy refers to the radiant light and heat emitted by the sun. It is a form of renewable energy that can be harnessed and converted into electricity or used for heating and lighting purposes. Solar energy is abundant and sustainable, making it an environmentally friendly alternative to fossil fuels. By harnessing solar energy, we can reduce our dependence on non-renewable energy sources and mitigate the negative impacts of climate change.Rate this question:

How does solar panels absorb solar energy?
- A.
By converting photons to electrons
- B.
By converting protons to electrons
- C.
By converting electrons to photons
- D.
By converting electrons to protons
Correct Answer
A. By converting pHotons to electronsExplanation
Solar panels absorb solar energy by converting photons (particles of light) into electrons. When sunlight hits the solar panel, it excites the electrons in the panel's semiconductor material, causing them to be released from their atoms. These free electrons are then captured and channeled into an electric current, which can be used to power electrical devices or stored for later use. This process is known as the photovoltaic effect and is the fundamental principle behind the functioning of solar panels.Rate this question:
