One reason JUUL and vape pens are so popular among teens currently might be that they can be used indoors without attracting unwanted attention or creating a stench, Morean says. On Twitter, teens post about their usage in school.
What is a star's emission spectrum? It is the same as the HR diagram and gives the same information. It is the fingerprint of all of the colors of light emitted by a star. It is a graph of all the pollution given off by a star. It is a graph of the starâs solar flares.
A Star with a peak wavelength of 4000 Angstroms. Because stars emit light with different wavelengths, they have different colors. Stars do not just emit one wavelength of electromagnetic radiation, but a range of wavelengths. If you look at the amount of light a star gives off at different wavelengths, you would get a graph like the one shown to the right. The wavelength at which a star emits the most light is called the star's peak wavelength. The diagram on the right shows that this star has a peak wavelength of 4000 Angstroms. Question 2.
