- Q2. What is mass of photon?
- Ans.
Photons are massless particles.
Photons are elementary particles that have zero rest mass.
They travel at the speed of light in a vacuum.
The energy of a photon is given by E=hf, where h is Planck's constant and f is the frequency of the photon.
The momentum of a photon is given by p=E/c, where c is the speed of light.
- Q3. What is de brogli wave?
- Ans.
De Broglie wave is a concept in quantum mechanics that describes the wave-like behavior of particles.
Proposed by Louis de Broglie in 1924
States that particles, such as electrons, can exhibit wave-like properties
The wavelength of the de Broglie wave is inversely proportional to the momentum of the particle
Used to explain phenomena like electron diffraction
