The electromagnetic (EM) spectrum encompasses the entire range of EM radiation. Radiation is the energy that travels and spreads out as it goes, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. A key relationship to remember is that frequency and wavelength are inversely proportional: higher frequency means shorter wavelength, and vice versa. Energy increases with frequency. Understanding these relationships is crucial for solving problems related to the EM spectrum.
Match the term with its correct definition:
| Term | Definition |
|---|---|
| 1. Wavelength | A. The number of waves passing a point per unit time. |
| 2. Frequency | B. Electromagnetic radiation with the shortest wavelengths. |
| 3. Gamma Rays | C. The distance between successive crests of a wave. |
| 4. Infrared | D. Electromagnetic radiation with wavelengths longer than visible light. |
| 5. Ultraviolet | E. Electromagnetic radiation with wavelengths shorter than visible light. |
Complete the following paragraph using the words: frequency, wavelength, energy, electromagnetic spectrum, inversely.
The _________ is the range of all types of EM radiation. The _________ and _________ of a wave are _________ proportional. Higher frequency means greater _________.
