NASA | IRIS: A Slice of Light

The video tutorial discusses NASA's Iris, a spectrograph that provides detailed images of the sun's chromosphere. It explains how Iris captures spectra by splitting light into discrete wavelengths, allowing scientists to measure temperature, velocity, and density of solar material. This data helps in understanding solar eruptions.

What is the significance of the chromosphere in the sun's atmosphere?

What kind of data does Iris provide, and why is it important?

Explain the process of how a spectrograph splits light into discrete wavelengths.
