Capitolo 6, Problema 44a
The hydrogen atom can absorb light of wavelength 1094 nm. (a) In what region of the electromagnetic spectrum is this absorption found?
Guida verificata passo dopo passo1
Identify the given wavelength of light absorbed by the hydrogen atom, which is 1094 nm.
Convert the wavelength from nanometers to meters for standard unit consistency. Use the conversion factor: 1 nm = 1 x 10-9 m.
Recall the regions of the electromagnetic spectrum and their corresponding wavelength ranges. The main regions include radio, microwave, infrared, visible, ultraviolet, X-rays, and gamma rays.
Determine which region the wavelength of 1094 nm falls into by comparing it to the known wavelength ranges of the electromagnetic spectrum. For example, the infrared region typically ranges from about 700 nm to 1 mm.
Conclude that the absorption of light by the hydrogen atom at 1094 nm falls within the infrared region of the electromagnetic spectrum.

Electromagnetic Spectrum
Wavelength and Energy Relationship
The energy of electromagnetic radiation is inversely related to its wavelength, described by the equation E = hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. Shorter wavelengths correspond to higher energy photons, while longer wavelengths correspond to lower energy. This relationship is essential for determining the energy associated with the absorption of light by atoms.
