Answer to Problem 56Q
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

- If a sunspot has a temperature of 4200 K and the average solar photosphere has a temperature of 5780 K, how much more energy is emitted in 1 second from a square meter of the photosphere compared to a square meter of the sunspot?
