Question

Bright Lines in pattern shows:

A.absorption

B.emission

C.emission

D.free particle


​

Answer 1

Answer:

This emission occurs when an atom, element or molecule in an excited state returns to a configuration of lower energy. ... Emission lines are usually seen as bright lines, or lines of increased intensity, on a continuous spectrum.

Answer 2

QUESTION:-

Bright Lines in pattern shows:

• A.absorption
• B.emission
• C.emission
• D.free particle

ANSWER:-

• Bright Lines in the pattern show emission.

• C.emission is the correct option.

EXPLANATION:-

• An emission is also known as a bright-line, spectrum.

• Atoms inundate and emit light, and the atoms of each element do so at certain and standard wavelengths. These wavelengths of light are spread out by a spectroscope from any source into bright coloured lines, a spectrum with a different pattern specifying each element.

• When light from a different source is assessed in a spectroscope, the several patterns of bright lines in the spectrum disclose which elements emitted the light. These patterns are called emission, or bright-line, spectrum.

• Absorption is the wrong answer because when light is passed through a gas or cloud at a temperature which is lower than the source of light then the gas is absorbed in its specifying wavelengths, and a dark line which is called absorption, the spectrum will be formed.
