Characteristics of Electromagnetic Waves

Characteristics of Electromagnetic Waves & Penetration Power of Radiation

- What is the wavelength & frequency of each wave?

- What is the order of EM waves according to energy?

In order from least to greatest energy: radio, microwave, infrared, visible light, ultraviolet, x-ray, and gamma-ray.

-What is the penetration power of radiation? Which two kinds of electromagnetic radiation are very penetrating?

The penetration power of radiation refers to its ability to pass through different materials. It varies depending on the type of radiation and its energy level. Radiation can be categorized into alpha particles, beta particles, gamma rays, and X-rays, each having different penetration capabilities. Radiation penetration power varies based on type and energy level. Alpha particles are stopped by paper or a few centimeters of air. Beta particles penetrate millimeters to centimeters of materials like plastic. Gamma rays and X-rays have high penetration power. They pass through most substances, including concrete, lead, and steel, but denser materials and thicker barriers reduce their penetration. Gamma rays and X-rays are used in medical imaging, industrial inspections, and research due to their ability to penetrate matter and provide valuable information.
