Why are x rays so much more powerfull than visible light rays?
X-rays have higher energy and shorter wavelengths than visible light rays, allowing them to penetrate deeper into materials and tissues. This property makes X-rays useful for imaging bones and other dense structures in the body. Additionally, the production of X-rays involves high-voltage electricity and specialized equipment, contributing to their higher power compared to visible light rays.
Which type of electromagnetic wave the sun gives off can be used for solar power?
The sun gives off mainly visible light and infrared radiation, which can be used for solar power through photovoltaic panels and solar thermal systems. These technologies capture the sun's energy and convert it into electricity or heat for various applications.
Would solar cells always extend plaing time on a wind up radio?
No, solar cells would only extend playing time on a wind-up radio if they are connected to a rechargeable battery that stores the energy produced. Directly connecting solar cells to the radio would only provide power when exposed to sunlight.
Direct solar heating refers to a system that uses sunlight to heat a space or water directly, without the need for complex systems or energy conversion. With direct solar heating, the heat from the sun is captured through windows, thermal collectors, or other means to warm up the area or liquid directly. This simple and efficient method can be used for both residential and commercial purposes to reduce energy costs and carbon emissions.
How long does it take to charge a 12 volt battery with a 45 watt solar panel?
It depends on the amp hour rating and discharge condition of the battery to start with. The output voltage of the solar cell should be at least 13 volts. At that voltage the cell has an output of 1.15 amps.
What enery transformed occur with a microwave?
Microwaves use electrical energy to generate electromagnetic radiation, which is absorbed by food molecules, causing them to vibrate and generate heat. This heat cooks the food quickly and efficiently.
How much power can solar panels hold when there's no sunlight?
Solar panels do not hold any power when there is no sunlight, as they require sunlight to generate electricity. However, some solar panel systems may have battery storage to store excess electricity generated during the day for use at night or on cloudy days.
Solar energy can be trapped through the use of solar panels, which convert sunlight into electricity. These panels are typically mounted on roofs or in open areas where they are exposed to direct sunlight. The electricity generated can then be used to power homes, businesses, or stored in batteries for later use.
What is the main ingredient in most solar cells?
The main ingredient in most solar cells is silicon. Silicon is a semiconductor material that is used to convert sunlight into electricity efficiently.
Solar panels convert sunlight into electricity through a process called the photovoltaic effect. This involves the absorption of solar energy by the panels' semiconductor material, which generates an electric current. This electricity can then be used to power homes, businesses, or stored in batteries for later use.
Can electricity be made From solar power?
Yes, electricity can be generated from solar power through the use of solar panels. Solar panels convert sunlight into electricity through the photovoltaic effect, where sunlight excites electrons in the panels to create an electric current.
How are solar cells today superior to solar cells of the 1980?
Advances in technology - coupled with the discovery of more efficient materials, make today's solar cells much more efficient than earlier models.
How can you compare the cost of regular electricity to the cost of solar electricity?
Solar is much more money because when you install it you don't pay for a month. Reg elecrtricty is better it never dies if the sun is not shining much or moonlight is not shining. You pay monthly. All By: Apple Gangsta A
Is biomass cheaper than solar power?
It depends on various factors such as location, scale of the project, availability of resources, and government incentives. In general, biomass can be cheaper in some regions due to the stable availability of feedstock, while solar power has become increasingly cost-effective due to advancements in technology and declining prices of solar panels.
With Which two forms of solar energy are we most familiar?
We are most familiar with photovoltaic solar energy, which uses solar panels to directly convert sunlight into electricity, and solar thermal energy, which uses sunlight to heat a fluid that can then be used for various applications such as generating electricity or heating water.
What do pants convert solar energy into?
Pants do not convert solar energy into anything. Pants are made of materials like cotton, denim, or synthetic fabrics, which do not have the capability to convert solar energy into another form.
Why is the back of a solar panels insulated?
The back of a solar panel is insulated to prevent any electrical components from coming into contact with external elements like moisture, dust, or debris. This insulation helps protect the electronics within the solar panel and ensures its longevity and performance.
How does solar energy heat up your home?
Solar energy heats up your home by harnessing sunlight through solar panels, converting it into electricity, and then using that electricity to power heating systems such as radiators or underfloor heating. This renewable energy source helps reduce reliance on traditional heating methods like natural gas or electricity, making it a more sustainable and cost-effective option for heating your home.
What do solar panels convert radiant energy into?
Solar panels convert radiant energy from the sun into electrical energy through the photovoltaic effect, where photons from the sun's rays dislodge electrons in the panel's semiconductor material, creating an electric current.
How many solar panels do you need to run your house?
The number of solar panels needed to run a house depends on factors such as energy consumption, location, roof size, and panel efficiency. On average, a typical household in the US may need between 20-30 solar panels to cover their energy needs. It is recommended to have a professional solar installer assess your specific requirements for an accurate estimate.
How increasing intensity of sun rays effect solar cell and solar panel?
Increasing intensity of sun rays will lead to higher power output from the solar cell and solar panel due to more photons hitting the surface and generating electricity. However, this can also cause the solar cell to heat up, potentially reducing its efficiency. It is important for solar panels to be designed with temperature management systems to ensure optimal performance.
Is solar power an option in the north pole?
Solar power may not be the most efficient option in the North Pole due to the long periods of darkness during winter. However, during the summer months when the sun is visible for 24 hours a day, solar power can be utilized effectively. To overcome the darkness in winter, other renewable energy sources like wind or geothermal power can be more reliable choices in the North Pole.
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.
What happens to the energy that is not usually transferred by the solar cells?
The energy that is not converted into electricity by solar cells is typically lost as heat. Solar cells are not 100% efficient at converting sunlight into electricity, so some energy is wasted in the form of heat as a byproduct of the conversion process.
Why is wind energy called solar energy?
Wind energy is indirectly derived from the sun because the uneven heating of the earth's surface by the sun creates wind patterns. As the sun heats the air at different rates, the air moves, creating wind. Therefore, wind energy is often referred to as a form of solar energy.
