Is de Broglie valid for photon?

As photon is a constituent of electromagnetic radiation (light) we can understand that it has both particle and wave like properties (wave-particle duality). So finally, the answer which is the sole objective of a question is: Yes. De brogile wave can be applied to a photon.

What did de Broglie say about light?

An early finding indicated that light can be regarded as both waves and particles. In 1924 Louis de Broglie introduced the idea that particles, such as electrons, could be described not only as particles but also as waves.

Does a photon of light have mass?

Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum.

What is de Broglie equation for a photon?

Derivation. de Broglie derived the above relationship as follows: 1) E = hν for a photon and λν = c for an electromagnetic wave. 2) E = mc2, means λ = h/mc, which is equivalent to λ = h/p.

Does light have a de Broglie wavelength?

The de Broglie wavelength of the photon is 442 nm. This wavelength is in the blue-violet part of the visible light spectrum.

Which of the following are characteristics of photon has?

The basic properties of photons are:

• They have zero mass and rest energy.
• They are elementary particles despite lacking rest mass.
• They have no electric charge.
• They are stable.
• They are spin-1 particles which makes them bosons.
• They carry energy and momentum which are dependent on the frequency.

What was the basic rationale behind de Broglie’s theory?

The De Broglie hypothesis proposes that all matter exhibits wave-like properties and relates the observed wavelength of matter to its momentum. After Albert Einstein’s photon theory became accepted, the question became whether this was true only for light or whether material objects also exhibited wave-like behavior.

Why does photon have zero rest mass?

The photons are said to be chargeless and massless particles that travel at the speed of light. So the rest mass of a photon is taken to be zero. This can be proved from Einstein’s special theory of relativity. Hence the photons have a rest mass of zero.

What unit is mass in de Broglie equation?

At non-relativistic speeds, the momentum of a particle is equal to its rest mass, m, multiplied by its velocity, v. The unit of the de Broglie wavelength is meters (m), though it is often very small, and so expressed in nanometers (1 nm = 10(-9) m), or Angstroms ( ).

What is the relationship which relates the wavelength of a photon to its mass?

The Compton wavelength of a particle is equal to the wavelength of a photon whose energy is the same as the mass of that particle (see mass–energy equivalence).
