Element discovered on the sun before earth?
Helium was first discovered in the spectrum of the sun before it was found on Earth. Scientists noted a yellow line in the solar spectrum during a solar eclipse in 1868, which was later determined to be due to the presence of helium.
what is the total range of energy which reaches the earth from the sun is called what?
The total range of energy that reaches the Earth from the Sun is called the solar spectrum. This spectrum includes various forms of electromagnetic radiation, such as visible light, ultraviolet, and infrared radiation. The solar spectrum is crucial for supporting life on Earth, driving weather patterns, and influencing climate.
What is the difference between solar flare and solar burst?
A solar flare is a sudden, intense eruption of radiation from the sun's surface, primarily occurring in the solar atmosphere and often associated with sunspots. It releases a vast amount of energy across the electromagnetic spectrum, including X-rays and ultraviolet light. In contrast, a solar burst typically refers to a brief emission of radio waves or particles, often linked to solar flares but not as energetic or broad in spectrum. Essentially, solar flares involve more energetic and diverse emissions, while solar bursts are more specific to radio frequencies.
Why it is justified to consider sun as a black-body for solar applications?
The sun can be considered a black body for solar applications because it emits radiation across a wide spectrum of wavelengths, closely resembling the ideal black-body radiation curve. Its surface temperature of approximately 5,500 degrees Celsius leads to an emission spectrum that aligns with Planck's law, allowing for predictable energy output. This simplification is useful for designing solar technologies, as it enables engineers to estimate the solar irradiance and optimize the efficiency of solar panels and other solar energy systems based on the sun's radiation characteristics.
What is the spectrum of the moon?
The moon reflects sunlight, so its spectrum is similar to that of the Sun. It follows a blackbody curve with peaks in the visible range. The moon also shows absorption lines from elements in its surface materials.

How does atomic spectrum differ from solar spectrum?
Atomic spectrum is produced when atoms emit or absorb light at specific energies, creating distinct lines or bands. Solar spectrum is the continuous spectrum of light emitted by the Sun, containing all wavelengths of light. Solar spectrum is produced by many elements and compounds in the Sun's atmosphere, creating a broad, continuous range of colors.

What does the spectrum of a solar prominence reveal?
The spectrum of a solar prominence reveals information about the elements present in the gas, the temperature, density, and motions of the material within the prominence, as well as magnetic fields influencing its behavior. By studying the spectrum, scientists can gain insights into the physical properties and processes occurring in solar prominences.
Why is the understanding of solar spectrum is important for designing of solar cells?
Understanding the solar spectrum is crucial for designing solar cells because it informs engineers about the different wavelengths of light that can be harnessed for energy conversion. Different materials have varying efficiencies at absorbing specific wavelengths; thus, knowing the spectrum allows for the selection of optimal semiconductor materials and structures. Additionally, it helps in maximizing the conversion efficiency by enabling the design of multi-junction cells that can capture a broader range of the spectrum. Ultimately, this knowledge leads to more efficient and cost-effective solar energy solutions.

Which part of the solar electromagnetic spectrum has the maximum intensity?
The visible light region of the solar electromagnetic spectrum has the maximum intensity. This is the range of wavelengths that our eyes are sensitive to, making it the most prominent part of the spectrum for us.

Can a spectrum be seen in a total solar eclipse?
During a TSE the Sun's corona can still be seen around the Moon. It provides some light which can be divided into a spectrum.
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.
