What is lambda max of Balmer series in H atom?

6568

How many spectral lines are in hydrogen?

four

How do you use spectral lines?

Spectral lines are often used to identify atoms and molecules. These “fingerprints” can be compared to the previously collected “fingerprints” of atoms and molecules, and are thus used to identify the atomic and molecular components of stars and planets, which would otherwise be impossible.

What do spectral lines look like?

Emission lines are seen as coloured lines on a black background. Absorption lines are seen as black lines on a coloured background. The presence of spectral lines is explained by quantum mechanics in terms of the energy levels of atoms, ions and molecules.

What do you understand by intensity of spectral lines?

The intensity of a spectral line at a given frequency is related to the net rate of absorption (or emission) at that frequency. The more intense the incident radiation, the greater the rate at which transitions are induced to the higher state and thus the stronger the absorbance of the sample.

What are the factors affecting intensity of spectral lines?

depends on:

• • the transition probability.
• between the two states.
• (selection rules)
• • population of states.
• • in absorption, the sample path length l.
• and concentration c (Beer-Lambert law)

On what factors intensity of spectral lines depends?

The intensity of lines on the spectrum will be affected by the amount of sample which light passes through. The intensity of this transmitted light depends on the sample concentration and path length.

Why do spectral lines have different brightness?

Explanation: The thickness (brightness) depends on the number of photons. When there is more frequency, there is more energy so it emits more photons.

Why does neon have so many spectral lines?

The spectrum of the neon light has several bright lines. The lines of light are produced when electrons in an excited state decays into a lower energy state. The change in energy of the electron between these two states is precise and results in the emission of light with a narrow range of energies, a spectral line.

Are LED lights continuous or line?

LED lights, or “Light Emitting Diodes,” as they are better known, emit a continuous spectrum. The spectrum they cover is not as broad as other colored lights or incandescent lights.

How many spectral lines wavelengths do we see from a red LED?

The light emitted by hydrogen atoms is red because, of its four characteristic lines, the most intense line in its spectrum is in the red portion of the visible spectrum, at 656 nm.
