Solution:
The wavelengths at which the photosphere, chromosphere, and corona emits the most radiation are
This result shows that the
Explanation of Solution
Given data:
The temperature of chromosphere is
The temperature of corona is
Formula used:
Wien’s law is written as,
Here,
Explanation:
Consider the average surface temperature of photosphere to be 5800 K.
Use Wien’s law for writing the expression for wavelength emitted by the photosphere.
Here, subscript 1 represents the corresponding quantities for photosphere.
Substitute
Since the wavelength of
Use Wien’s law for writing the expression for wavelength emitted by the chromosphere.
Here, subscript 2 represents the corresponding quantities for chromosphere.
Substitute
Since the wavelength of
Use Wien’s law for writing the expression for wavelength emitted by the corona.
Here, subscript 2 represents the corresponding quantities for corona.
Substitute
Since the wavelength of
Chromosphere and corona emit light of short wavelength, which is not clearly seen by the observer. For getting a clear picture of corona and chromosphere, space station is used.
Conclusion:
Hence, the wavelengths at which the photosphere, chromosphere, and corona emit the most radiation are

- Tutorial Star A has a temperature of 6,000 K. How much energy per second (in J/s/m²) does it radiate onto a square meter of its surface? If the temperature of Star A decreases by a factor of 2, the energy will decrease by a factor of Star B has a temperature that is 5 times higher than Star A. How much more energy per second (compared to Star A) does it radiate onto a square meter of its surface? Part 1 of 4 The energy of a star is related to its temperature by E = OTA where o = 5.67 x 10-8 J/s/m²/K4. Part 2 of 4 To determine how much energy Star A is radiating, we just plug in the temperature to solve for EA.
