Electromagnetic waves consist of electric and magnetic fields having the same phase
how?
how?
Well,I'm interested in digging into Maxwell's equations but I'm still at school and I have no time for something like thisMisr - afraid not. If you're not willing or able to dig into the Maxwell equations you shouldn't be too worried about the phase relationship between E and B fields either. Is the question really so important to you? And if it is - which is great - why don't you want to go into the subject more deeply? Although I must say this - without calculus including vector calculus you won't get very far.
There is however a publication called 'The Radio Amateur's Handbook' published by ARRL, also "The AARL Antenna Book'. Both those pubs address e-m waves in a non-calculus manner, and they might answer your question adequately or they may not.

I read the statement above in my textbook"Electromagnetic waves consist of electric and magnetic fields having the same phase"
and I couldn't understand it but I didn't know that the subject is complicated
Thanks very much
Electromagnetic waves are a type of energy that are generated by the movement of electrically charged particles, such as electrons. They consist of oscillating electric and magnetic fields that travel through space at the speed of light.
Electromagnetic waves are created when an electrically charged particle, such as an electron, is accelerated. This acceleration causes a disturbance in the electric and magnetic fields, which then radiates outwards as an electromagnetic wave.
Electromagnetic waves are a broad spectrum of energy, including radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Light refers specifically to the portion of the electromagnetic spectrum that is visible to the human eye.
Electromagnetic waves have a wide range of practical applications in our daily lives. Radio waves are used for communication, microwaves for cooking, infrared radiation for remote controls and thermal imaging, visible light for vision, ultraviolet radiation for sterilization, X-rays for medical imaging, and gamma rays for cancer treatment.
Some forms of electromagnetic waves, such as X-rays and gamma rays, can be harmful to humans in high doses. However, exposure to low levels of electromagnetic waves, such as those from radio waves and visible light, is not known to have any negative effects on human health.
