WebIR can be absorbed and emitted by atoms and molecules, particularly between closely spaced states. IR is extremely strongly absorbed by water, for example, because water molecules have many states separated by energies on the order of 10 –5 eV to 10 –2 eV, well within the IR and microwave energy ranges. WebChemists study how different forms of electromagnetic radiation interact with atoms and molecules. This interaction is known as spectroscopy. Just as there are various types of …

WebThe wavelength (λ) of the light emitted by a hydrogen atom that has an initial configuration of 5s¹ is as follows, 1/ λ = R [ 1 / (n₁)² - 1 / (n₂)² ] …(1) Here,n₁ represents the level of lower energy orbital, n₂ represents the level of higher energy orbital and R is the Rydberg constant with a value of 1.097 10⁷ m⁻¹. WebThe classical example of a continuous spectrum, from which the name is derived, is the part of the spectrum of the light emitted by excited atoms of hydrogen that is due to free electrons becoming bound to a hydrogen ion and emitting photons, which are smoothly spread over a wide range of wavelengths, in contrast to the discrete lines due to … WebThe frequencies of light that an atom can emit are dependent on states the electrons can be in. When excited, an electron moves to a higher energy level or orbital. When the electron falls back to its ground level the light is emitted. Emission spectrum of hydrogen The above picture shows the visible light emission spectrum for hydrogen. oracle common user
