Why does hydrogen have a line spectrum and not continuous?
Remember that the hydrogen spectrum is not a continuous spectrum. It’s a set of discrete lines determined by the changes in energy a hydrogen atom undergoes when exposed to energy. It gives off photons of discrete energies/wavelengths, hence the color of the lines.
Why does sunlight have a continuous spectrum?
When the light leaves the surface of the Sun, it is very nearly a continuous spectrum. However, as it passes through the Sun’s atmosphere, gasses present in that atmosphere absorb specific wavelengths of light, leaving the pattern seen in the spectrum above.
How is the spectrum of hydrogen atoms different from a continuous spectrum?
Atoms of individual elements emit light at only specific wavelengths, producing a line spectrum rather than the continuous spectrum of all wavelengths produced by a hot object.
Why does hydrogen produce light in distinct lines instead of a continuous color spectrum?
Although hydrogen has only one electron, it contains many energy levels. When its electron jumps from higher energy level to a lower one, it releases a photon. Those photons cause different colours of light of different wavelengths due to the different levels. Those photons appear as lines.
Why is line spectrum not continuous?
Quick answer: Atomic spectra are continuous because the energy levels of electrons in atoms are quantized. The electrons in an atom can have only certain energy levels. Each packet of energy corresponds to a line in the atomic spectrum. There is nothing between each line, so the spectrum is discontinuous.
Is hydrogen spectrum continuous?
Effect of the source on the continuous spectrum of hydrogen—The continuous spectrum of hydrogen is observed to be of similar character, although of differing intensity, in a number of sources, a Wood tube, an ordinary discharge tube, the separate striations of the positive column, the condensed spark in hydrogen at …
What is the hydrogen emission spectrum?
When an electric current is passed through a glass tube that contains hydrogen gas at low pressure the tube gives off blue light. When this light is passed through a prism (as shown in the figure below), four narrow bands of bright light are observed against a black background.
How are the visible lines created in hydrogen?
In the simplified Rutherford Bohr model of the hydrogen atom, the Balmer lines result from an electron jump between the second energy level closest to the nucleus, and those levels more distant. For hydrogen (Z = 1) this transition results in a photon of wavelength 656 nm (red).
Which light source produces a continuous and line spectrum?
An incandescent light bulb produces a continuous spectrum because the source of the light is a metal filament (wire). A continuous spectrum emanates from the dark parts of the universe.
Does the Sun have a continuous or non continuous spectrum?
We have two type of atoms comprising most of the sun’s structure: hydrogen and helium. And these have a noncontinuous spectrum. But the sun has a continuous spectrum like a black body radiation because of free to bond or free to free radiation.
What is the emission spectrum of a heated gas?
spectra from heated gas was studied extensively in the 1800’s. It was realized that a heated gas emits a unique combination of colors, called emission spectrum, depending on its composition. Example: Helium gas in a discharge lamp. Main idea: put a large voltage across the gas. It will break down and emit light. The light emitted is
What is the difference between emission spectrum and absorption spectrum?
An emission spectrum can be produced by a gas at low pressure excited by heat or by collisions with electrons. An absorption spectrum results when light from a continuous source passes through a cooler gas, consisting of a series of dark lines characteristic of the composition of the gas.
What gives off blue light when hydrogen gas is passed through?
Emission Spectrum of Hydrogen When an electric current is passed through a glass tube that contains hydrogen gas at low pressure the tube gives off blue light. When this light is passed through a prism (as
