Broad spectrum

Broad Spectrum refers to a term often used in various fields such as medicine, biology, chemistry, and communications. In each context, it carries a different meaning but generally implies a wide range or variety.

Medicine

In medicine, the term broad spectrum is commonly associated with antibiotics. A broad-spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, Gram-positive and Gram-negative, or any antibiotic that acts against a wide range of disease-causing bacteria. These antibiotics are often used to treat infections when the causative organism is unknown.

Biology

In biology, broad spectrum may refer to the range of organisms that a certain substance or action affects. For example, a broad-spectrum pesticide will kill a wide range of pests, not just a specific type.

Chemistry

In chemistry, broad spectrum can refer to a substance that interacts with a wide range of chemical structures or has a wide range of reactivity.

Communications

In communications, broad spectrum refers to a range of frequencies, wavelengths, or colors. For example, a broad-spectrum light source emits light over a wide range of wavelengths.
