That is, if you observe the spectrum of a star and can determine the wavelength where the emission peaks (Î»max), you can calculate that starâs temperature. Here is another copy of the plot that we studied in Lesson 3: Figure 4.1: Two-dimensional plot of the spectrum of a blackbody with different temperatures.
Igneous rocks usually contain the most crystals. The longer it takes the magma to cool, the larger the crystals.
An igneous rock is a rock that is made from heat, and the different types of igneous rocks are Obsidian, Granite, Basalt, Pumice and Gabbro.n igneous rock is a rock that is made from heat, and the different types of igneous rocks are Obsidian, Granite, Basalt, Pumice and Gabbro.
