EM waves affect us in various ways depending on their frequency and intensity. Low-frequency waves like radio waves are generally safe, while high-frequency waves, such as X-rays, can be harmful with prolonged exposure. Common effects include heat from microwaves and UV radiation from the sun, which can cause skin burns or cancer. To protect yourself, limit exposure to high-frequency EM waves and use protective measures like sunscreen for UV rays.
