Hii ni case kwa photons peke yake ila sio general rule
Dah!!! Hapa tunaongelea electromagnetic yote. Na ndiyo inayotumika kwa asilimia kubwa kwenye current technologies.
Ni vyema kwanza ukakubali kuwa energy is not interchangeable to matter.
Electromagnetic energy is the energy associated with electromagnetic radiation, which includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. The energy of electromagnetic radiation is proportional to its frequency and can be calculated using the following formula:
E = h * f
where E is energy, h is Planck's constant (6.626 x 10^-34 joule seconds), and f is frequency (measured in hertz, or cycles per second).
For example, consider a beam of green light with a frequency of 5.4 x 10^14 hertz. The energy of this beam of light can be calculated using the formula:
E = h * f = (6.626 x 10^-34 J s) * (5.4 x 10^14 Hz) = 3.58 x 10^-19 joules
This means that each photon of this green light beam has an energy of 3.58 x 10^-19 joules.
Another example is X-ray radiation with a frequency of 2.4 x 10^18 Hz. The energy of this X-ray radiation can be calculated using the same formula:
E = h * f = (6.626 x 10^-34 J s) * (2.4 x 10^18 Hz) = 1.59 x 10^-15 joules
This means that each X-ray photon has an energy of 1.59 x 10^-15 joules.
The formula for electromagnetic energy is a fundamental equation in physics and has many applications, including in the design of technologies that use electromagnetic radiation such as solar cells, medical imaging devices, and wireless communication systems.
