why do electric and magnetic fields have no effect on an electromagnetic wave?

Hernik said:Is it because the electromagnetic wave has no charge?
Vanadium 50 said:So there is no reason a field cannot act on another field, and there are counterexamples: a changing electric field produces a magnetic field.
Vanadium 50 said:That's true, but the key word is "electric". It's a statement about the kinds of fields, not a statement about fields.
Electromagnetic radiation is a type of energy that is present in the form of waves or particles. It includes a wide range of wavelengths, from shorter wavelengths such as gamma rays and X-rays to longer wavelengths such as radio waves and microwaves.
Electromagnetic radiation is produced by the movement of electrically charged particles. This can occur naturally, such as in the form of sunlight or lightning, or it can be produced artificially through processes such as radio waves in communication devices or X-rays in medical imaging.
Electromagnetic radiation has several key properties, including wavelength, frequency, and energy. Wavelength is the distance between two consecutive peaks or troughs in a wave, while frequency is the number of waves that pass a given point in one second. The energy of electromagnetic radiation is directly proportional to its frequency and inversely proportional to its wavelength.
Electromagnetic radiation can interact with matter in several ways. It can be absorbed, reflected, or transmitted by different materials depending on their properties. For example, X-rays are easily absorbed by dense materials like bones, while radio waves can pass through most objects with little interference.
The potential health effects of electromagnetic radiation depend on the type, intensity, and duration of exposure. Some forms of radiation, such as ultraviolet and X-rays, can be harmful to living organisms, while others like visible light and radio waves typically do not pose a significant health risk. Proper shielding and safe handling practices can help minimize potential health effects of exposure to electromagnetic radiation.
