The year that Albert Einstein found mass energy equlivalance was in 1825...
No. Sound is mechanical energy. Mechanical energy does not have mass. And no form of energy has mass. But energy has a mass equivalent per E=mc2 thanks to Albert Einstein.
Albert Einstein
Any energy - including light - has an associated mass.
the mass energy equivalence formula
Albert Einstein
albert Einstein
Albert Einstein's famous equation E=mc^2 shows the relationship between mass and energy, proposing that mass can be converted into energy. This theory revolutionized our understanding of the universe and has profound implications in fields like nuclear physics and energy production.
special relativity
his theory of relativity. E=mc2 saying mass is energy energy is mass. and comparing space and time the same way .
Energy equals mass times the SPEED of light squared
Albert Einstein
In the beginning of the 20th century. He proposed mass-energy equivalence in 1905, and set out to mathematically express this. E = mc2 shows that energy can be converted into mass, and mass into energy. Thus, we no longer say that mass is conserved, or energy is conserved. But rather, we say that mass-energy is conserved.
