Which process is responsible for the energy emitted from the sun and all other stars?
The process responsible for the energy emitted from the sun and all other stars is nuclear fusion. This process involves the fusion of hydrogen nuclei to form helium under extreme pressures and temperatures, releasing vast amounts of energy in the form of light and heat.
How can two stars have the same absolute magnitude but be differents sizes?
The idea is that a larger star may be cooler - emit less energy per square meter of surface. The total energy emitted is equal to the surface area, multiplied by the energy emitted per unit area.
Do hotter stars radiate more energy at higher frequencies?
Yes, hotter stars radiate more energy overall, with a greater proportion emitted at higher frequencies. This is due to the relationship between temperature and the peak wavelength of light emitted, known as Wien's Law. As a star's temperature increases, the peak wavelength shifts towards shorter, higher-energy wavelengths.
What type of energy is received on earth from the sun and other stars?
Heat, visible light, and infrared light (UV Rays) are the three main types of energy emitted from the sun and stars. Although, around 30% of it does get forced back into space.
What is the constant outward release of tiny particles caused by stars energy production?
Stars are balls of gasses in plasma form. The high pressure and temperature in the core of the stars ignites a nuclear fusion reaction, that is the source of the light and energy emitted by them.
The temperature and brightness of stars are indicated by their what?
The temperature of stars is indicated by their color, with cooler stars appearing more red and hotter stars appearing bluer. The brightness of stars is measured in terms of luminosity, which is the total amount of energy emitted per unit of time.
What makes some stars look brighter then others?
How big, how hot (color/amount of energy emitted), how far, light pollution at viewing site
Why are dwarf stars dim?
Dwarf stars are dim because they are smaller and cooler than other types of stars. Their lower temperature and smaller surface area result in less light being emitted compared to larger, hotter stars. This makes them appear dimmer when observed from a distance.
What term is energy emitted as electromagnetic waves?
The term for energy emitted as electromagnetic waves is radiation.
How does the change in energy level compare to the energy of the emitted photon?
The change in energy level of an atom corresponds to the energy of the emitted photon. When an electron transitions from a higher energy level to a lower one, the energy difference between these levels is released in the form of a photon. The energy of the emitted photon can be calculated using the equation (E = h \nu), where (E) is the energy change, (h) is Planck's constant, and (\nu) is the frequency of the emitted photon. Thus, the energy of the emitted photon directly reflects the magnitude of the change in energy level.
What energy is emitted as electromagnetic waves?
radiant energy
