If you take an outdoor photo through a bandpass filter that only let's light through in a Fraunhofer line would it be completely dark, like night? Or would it have some daytime illumination?
Fraunhofer lines refer to dark lines that are observed in the solar spectrum. These lines are caused by the absorption of specific wavelengths of light by elements in the Earth's atmosphere.
A bandpass filter is used to block out unwanted light and only allow specific wavelengths of light to pass through. This can help to enhance certain features or colors in the photo, such as the Fraunhofer lines.
Fraunhofer lines can add interesting and unique patterns to outdoor photographs, especially when using a bandpass filter. They can also provide information about the composition of the Earth's atmosphere at the time the photo was taken.
Yes, Fraunhofer lines can be used to study the Sun's atmosphere. By analyzing the wavelengths of light that are absorbed by the elements in the Sun's atmosphere, scientists can learn about the composition and temperature of the Sun's outer layers.
Fraunhofer lines are named after the German physicist Joseph von Fraunhofer, who first observed and catalogued them in the early 1800s. The lines are typically referred to by a letter or number, based on their position in the spectrum.
