A star has radius R=1.90x10^9 m and surface temperature T=15,200K. How much power does it emit in the range 500 nm < lamda < 510 nm?
It is what it is. Can you use the information from the link I posted, or your text, and the surface area of the star to find the answer?agentsmith1011 said:4*pi()*R^2...But I wish it is pi()*R^2
"Star Power Emission: 500nm-510nm" refers to the specific range of wavelengths of light emitted by a star. It falls within the green portion of the visible light spectrum.
The 500nm-510nm range is important because it is the range of wavelengths that corresponds to the color green. This can provide valuable information about the composition and temperature of a star.
The 500nm-510nm range is measured using a spectrophotometer, which separates light into its different wavelengths and measures the intensity of each wavelength. The intensity of light in this range can be used to calculate the star's luminosity and temperature.
The 500nm-510nm range can tell us about a star's temperature, composition, and age. For example, a star with a higher intensity in this range may be younger and hotter, while a star with a lower intensity may be older and cooler.
The 500nm-510nm range can vary among different types of stars. For example, a blue star may have a higher intensity in this range compared to a red star, as blue stars are typically hotter and emit more energy in the visible light spectrum.
