a) Spectroscopy is the study of the interaction between matter and electromagnetic radiation. It involves analyzing the way in which different substances absorb or emit light at different wavelengths. Spectroscopy is used in various scientific fields, such as chemistry, physics, and astronomy.
Example: In chemistry, spectroscopy is used to identify the chemical composition of a substance by analyzing the pattern of light absorption or emission.
b) Characteristic spectra refer to the unique pattern of spectral lines produced by a specific element or compound. These spectra are used to identify and analyze the composition of substances based on the wavelengths of light they absorb or emit.
Example: The characteristic spectra of hydrogen gas consist of a series of discrete lines at specific wavelengths, which can be used to identify the presence of hydrogen in a sample.
c) Continuous spectra refer to a broad, continuous range of wavelengths of light without any distinct lines or bands. This type of spectrum is produced by hot, dense objects, such as stars or incandescent light bulbs.
Example: The light emitted by an incandescent light bulb produces a continuous spectrum, with all wavelengths of visible light present.

a) Spectroscopy:
Spectroscopy is the study of the absorption and emission of electromagnetic radiation by matter. It involves using spectroscopic methods to analyze the interaction of matter with different wavelengths of light, ranging from gamma rays to radio waves.
- Example: Atomic spectroscopy examines the absorption or emission of light by atoms, providing information about their energy levels and electronic structure.
b) Characteristic Spectra:
Characteristic spectra are unique patterns of absorption or emission lines that are specific to a particular element or molecule. These spectra provide information about the atomic or molecular structure and can be used for identification purposes.
- Example: The emission spectrum of hydrogen, which consists of a series of discrete lines, is a characteristic spectrum that can be used to identify the presence of hydrogen in a sample.
c) Continuous Spectra:
Continuous spectra are those in which there are no sharp lines or bands. Instead, the intensity of the radiation gradually varies across a range of wavelengths.
- Example: The spectrum of a hot incandescent light bulb is a continuous spectrum, as it contains all wavelengths of visible light.
