e =mc2. e = hf
is it different?
than why??
..e =mc2 this only use in nuclear??

The equation e = mc2, also known as Einstein's famous mass-energy equivalence, states that mass (m) and energy (e) are two forms of the same thing, with the speed of light (c) being the conversion factor between them.
Einstein developed the equation as part of his theory of special relativity in 1905. He observed that the laws of physics are the same for all observers moving at a constant velocity, and that the speed of light is the same for all observers regardless of their motion. From these principles, he derived the equation e = mc2.
The first equation, e = mc2, relates mass and energy, while the second equation, e = hf, relates energy and frequency. The "c2" factor in the first equation represents the speed of light, while the "h" in the second equation represents Planck's constant.
Einstein's famous equation e = mc2 can be derived from the equation e = hf by substituting the frequency (f) with the speed of light (c) divided by the wavelength (λ). This shows the fundamental relationship between mass, energy, and frequency in the universe.
Yes, e = mc2 is still a fundamental principle in modern physics. It has been experimentally verified countless times and is used in various fields such as nuclear physics, particle physics, and astrophysics. The equation also has practical applications, such as in nuclear energy and medical imaging technology.
