Aspects of the Sun observed at different spectral ranges

The search for new methodologies and strategies to bring physics classes closer to the reality of high school students, prompts teachers to create new activities with novel ideas, different from those that are usually found in textbooks.

In this context, the Sun was used as a known basis to explain the concepts of electromagnetic waves and black body radiation, approaching this content with the use of the Planck function, the Wien’s law and the Stefan-Boltzmann law in practical activities by using a code developed by us, and astronomical images obtained through cutting edge technology, making the learning process more significant.

The goal is to present the possibility of using information related to the Sun as a guiding theme for the learning of Modern Physics topics, motivating students during the educational process. In addition, a summary of the basic concepts related to the Sun is presented, endeavoring to provide teachers with a way to understand the physical processes that explain how different solar characteristics are observed in specific spectral ranges.
