A hydrogen atom has only one electron, yet it contains a large number of shells. So, when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released. Hence, mono-electronic hydrogen has many spectral lines.
Q. What causes the spectral lines to appear?
Spectral lines are produced by transitions of electrons within atoms or ions. As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed.…

Q. What accounts for the existence of large no of lines in hydrogen spectrum?
A hydrogen atom contains only one electron, but this electron can be raised to higher energy states. The large number of spectral lines in hydrogen atom spectrum are due to the fact that a large number of transitions of the electron can take place between the different energy states.
Q. What are two light sources you should not look at with a spectroscope?
You can also examine sunlight, though you should NEVER LOOK DIRECTLY AT THE SUN THROUGH YOUR SPECTROSCOPE. Instead, aim your instrument at the light bouncing off of a white wall.
Q. What can you see with a spectroscope?
A spectroscope is used to determine the atomic makeup of a visible source of light; a star, planet, or light bulb for instance. White light is actually made up of many different colors of light; red, blue, green, yellow all the colors imaginable really (except black, which is defined as the absence of light).
Q. What does a spectroscope tell you?
Spectrographs collect data that tell scientists how much light comes out at each wavelength. These data reveal important details about the makeup of atmospheres on exoplanets, the compositions of stars and nebulas, the motion of galaxies and more.
Q. What does a spectroscope do to light that enters it?
Light entering a spectroscope is carrying spectral information. The information is decoded by splitting light into its spectral components. In its simplest form, a spectroscope is a viewing instrument consisting of a slit, a collimator, a dispersing element, and a focusing objective (see Figure 1).
Q. What is the difference between a spectroscope and a spectrograph?
A spectroscope is a device that measures the spectrum of light. A spectrograph is an instrument that separates incoming light by its wavelength or frequency and records the resulting spectrum in some kind of multichannel detector, like a photographic plate.
