derive the de brogile wave equation what is meant by dual nature of matter
Answers
Explanation:
De Broglie first used Einstein's famous equation relating matter and energy:
with
E = energy,
m = mass,
c = speed of light
Using Planck's theory which states every quantum of a wave has a discrete amount of energy given by Planck's equation:
with
E = energy,
h = Plank's constant (6.62607 x 10-34 J s),
ν= frequency
Since de Broglie believed particles and wave have the same traits, he hypothesized that the two energies would be equal:
Because real particles do not travel at the speed of light, De Broglie submitted velocity (v) for the speed of light (c).
Through the equation λ, de Broglie substituted v/λ for ν and arrived at the final expression that relates wavelength and particle with speed.
Hence
This is known as de Broglie wave equation and λ is known as de Broglie wavelength.

⭐The Dual Nature of Matter⭐
=> de-Broglie's Principle states that "All material particles in motion possess wave characteristics..."
=> de-Broglie's Relationship can be derived by combining the mass and energy relationships proposed by Max Planck, and Albert Einstein...
E = ∫c²dm = Σc²Δm = mc²
E = hν
=> The combination of these two yielded the desired result:
λ = h/mc
=> The above equation is valid for a Photon(γ⁰)
=> The same relation can be extended to every particle of this universe, if the speed of light in vacua(c) is replaced by the ordinary velocity of the particle:
