Question

for what purpose the de broglie equation is used

Answer 1

Answer:

calculate wavelength

Explanation:

E=mc^2

E=hc/lambda

so

mc^2=hc/lambda

lambda=h/mc

Answer 2

⭐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(γ ⁰)

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:

$\: \: \: \: \: \: \: \: \: λ = \frac{h}{ \: mv⃗}$
