Understand that the potential danger associated with exposure to an electromagnetic wave increases proportionally with its frequency.
Describe the harmful physiological effects of excessive exposure to various types of electromagnetic radiation, including internal heating from microwaves, skin burns from infrared, cellular damage from ultraviolet, and cellular mutation from X-rays and gamma rays.
Evaluate the practical applications of different types of electromagnetic radiation across fields such as communication, medicine, security, and domestic appliances.
Understand that radio waves can be generated by oscillations in electrical circuits, and conversely, they can induce such oscillations.
Explain how changes in atomic and nuclear structures can generate a wide spectrum of radiations, and how the absorption of these radiations can trigger subsequent atomic changes.
