How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
Which property of sodium is being used in street light?
The property of sodium being used in street lights is its ability to produce a bright yellow light when excited by electricity. This is a result of the characteristic emission spectrum of sodium, which makes it an efficient and effective choice for lighting public areas at night.
Why do you only see four lines in the emission spectrum of Hydrogen?
The hydrogen atom has four spectral lines because it undergoes transitions between its energy levels. These transitions produce four distinct wavelengths of light in the visible spectrum: 656.3 nm, 486.1 nm, 434.0 nm, and 410.2 nm. Each line corresponds to electrons moving between different energy levels in the atom.
Which type of spectrum can be produced by solid liquid or gas?
The spectrum produced by solid is continuous spectrum. Continuous spectrum is formed by all, solid liquid and gases if the pressure is high. In case of low pressure, gases produce line spectrum.
What causes the color when you burn an element?
The color produced when burning an element is due to the emission of light by the excited electrons in the atoms of that element. The energy absorbed during heating causes the electrons to jump to higher energy levels, and when they return to their original levels, they release this energy in the form of light, leading to the observed color.
What element can produce an atomic emission spectrum in its natural state neon chlorine silicon or Krypton?
Every element can produce an emission spectrum, if it is sufficiently heated. Of the 4 elements that you mention, neon is the most useful, in terms of its emission spectrum, and it is used in a certain type of lighting.
What does a hydrogen atom transitioning from the 2nd to the 1st excited state produce?
A hydrogen atom transitioning from the 2nd to the 1st excited state produces a photon of ultraviolet light. This ultraviolet light has a specific wavelength corresponding to the energy difference between the two states.
What is the name of the spectrum when elements produce different colors when heated?
The spectrum produced when elements emit different colors when heated is called an emission spectrum. Each element has a unique emission spectrum based on the specific wavelengths of light it emits.
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
Why cant an atom in the ground state produce emission lines?
An atom in the ground state does not have any electrons excited to higher energy levels. Without these excited electrons transitioning back to lower energy levels, there is no emission of photons with specific wavelengths that correspond to emission lines.
What kind of spectrum does a neon sign produce?
A neon sign produces an emission spectrum, which is characterized by bright, colorful lines of light at specific wavelengths. This is due to the electrons in the neon gas being excited and emitting photons of light as they return to their ground state.
What is the difference between sunlight produced spectrum and hydrogen gas produced spectrum?
Sunlight produced spectrum is continuous and contains a broad range of wavelengths, while hydrogen gas produced spectrum consists of discrete lines at specific wavelengths due to the unique energy levels of hydrogen atoms. Sunlight spectrum is continuous due to the various processes that produce light, whereas hydrogen gas spectrum is a result of the energy levels of hydrogen atoms emitting photons of specific wavelengths.

What color flame does potassium ions produce in a flame emission photometer?
Potassium ions produce a lilac or light pink flame when using a flame emission photometer. The color is distinct and helps to identify the presence of potassium in a sample based on the emission spectrum produced when the sample is exposed to heat in the flame.
Which type of spectrum can be produced by solid liquid or gas?
The spectrum produced by solid is continuous spectrum. Continuous spectrum is formed by all, solid liquid and gases if the pressure is high. In case of low pressure, gases produce line spectrum.
