Health Effects of Electromagnetic Waves

The video tutorial explains the electromagnetic spectrum, detailing each type of wave from gamma rays to radio waves. It covers their characteristics, uses, and potential risks. Gamma rays have the highest frequency and are used in radiotherapy but can cause radiation sickness. X-rays are used in medical imaging but can damage cells. Ultraviolet rays aid in vitamin D production but can cause skin cancer. Visible light is essential for vision but can harm eyes. Infrared radiation is experienced as heat and used in thermal imaging. Microwaves are used in communication but can heat body tissues. Radio waves are used in broadcasting and are generally safe.
