Photons are elementary particles that deliver the energy contained within electromagnetic radiation. The amount of energy a photon carries is directly related to a wave's frequency; therefore, higher-frequency waves deliver more energetic photons than lower-frequency waves.

Frequency is defined as the number of waves that pass a specific point in a given period of time. There is an inverse relationship between a wave's frequency and its wavelength; longer wavelengths correspond to lower frequencies, while shorter wavelengths are associated with higher frequencies.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.
