- 1. Electromagnetic Spectrum Overview, Properties,and Applications
- 2. Introduction • • Theelectromagnetic spectrum is the range of all types of EM radiation. • • Radiation is classified by wavelength or frequency. • • Includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Diagram of EM Spectrum
- 3. Divisions of Electromagnetic Spectrum •• Radio Waves – Communication, Broadcasting • • Microwaves – Radar, Cooking • • Infrared – Remote sensing, Night vision • • Visible Light – Human vision, Photosynthesis • • Ultraviolet – Sterilization, Fluorescence • • X-rays – Medical imaging • • Gamma Rays – Cancer treatment, Nuclear reactions Spectrum Chart
- 4. Properties of Electromagnetic Waves •• Travel at the speed of light in vacuum (3 × 10^8 m/s). • • Transverse waves with electric and magnetic components. • • Can travel through vacuum (do not require medium). • • Carry energy and momentum. Wave Diagram
- 5. Applications of Electromagnetic Spectrum •• Radio waves – Broadcasting, Communication • • Microwaves – Mobile phones, Radar • • Infrared – Thermal imaging, Remote controls • • Visible light – Optical devices, Illumination • • Ultraviolet – Sterilization, Tanning • • X-rays – Medical diagnosis, Security scanning • • Gamma rays – Cancer therapy, Sterilizing equipment Radio/TV Image Medical X-ray Image Gamma Therapy Image
- 6. Conclusion • • Theelectromagnetic spectrum spans a wide range of wavelengths and frequencies. • • Each region has unique properties and applications. • • Essential in science, technology, and daily life.
