Which equation was used by Albert Einstein to explain the photoelectric effect?

Einstein used the equation E = hf to explain the photoelectric effect, where E is the energy of a photon, h is Planck's constant, and f is the frequency of the light. This equation shows that the energy of a photon is directly proportional to its frequency.


In Albert Einstein's famous equation e equals mc squared what does the letter c represent?

In the equation E=mc^2, the letter c represents the speed of light in a vacuum. It is a constant value equal to approximately 299,792,458 meters per second.


Who developed the equation e equals mc2?

The equation E=mc^2 was developed by physicist Albert Einstein in 1905 as part of his theory of special relativity. It describes the equivalence of energy (E) and mass (m) and the constant speed of light (c) in a vacuum.


What might be the fudge factor in the Einstein equation?

The fudge factor in the Einstein equation refers to the cosmological constant denoted by the symbol Λ, which Einstein originally introduced to achieve a static universe. The cosmological constant represents a repulsive force that counteracts gravity on cosmological scales, leading to the accelerated expansion of the universe in the current understanding of cosmology.


What was Einstein's thought about light?

He hypothesized that the speed of light is constant, no matter what the frame of reference is.


What is the Planck-Einstein equation?

The Planck-Einstein equation describes the energy of a photon, which is a quantum of light. It states that the energy of a photon is directly proportional to its frequency, with the constant of proportionality being Planck's constant. This equation helps to quantify the energy carried by individual photons in electromagnetic radiation.


Who discovered the equation energy times speed of light squared?

Einstein


What did albert Einstein's famous equation stand for?

E=mc2 E=energy m=mass c=speed of light Einstein's equation states that Energy equal mass times the speed of light squared


What physical phenomenon does the formula describes?

The formula E=mc^2 describes the relationship between energy (E), mass (m), and the speed of light (c). It shows that energy and mass are interchangeable, with a constant factor being the square of the speed of light. It is a fundamental equation in physics, derived by Albert Einstein as part of his theory of relativity.


What does Einstein's famous equation E equals mc2 stand for?

The energy (E) in any body of matter is equal to its mass (M) times the square of the speed of light (C2)


What did albert einstein say about light?

Albert Einstein proposed that the speed of light is constant in a vacuum and that light can behave as both a particle and a wave, known as wave-particle duality. He also introduced the theory of relativity, which revolutionized our understanding of time, space, and gravity.


When did Albert Einstein figure out that emc2?

Einstein first published his theory that E = mc2 in 1905. You forgot the = sign, which is pretty important, since the formula means that the energy of an object is equal to its mass times the square of the speed of light.
