Question

DOES PHOTONS HAVE DE BROGLIE WAVELENGTH?EXPLAIN

Answer 1

we know that.. photons have rest mass equal to zero but photons carry momentum

=) p = E/C -------------(1)

but we know that energy of photon

=) E = hv -------------( 2 )

here" h" is plank's constant

and 'v ' is frequency of source

by plank's quantum theory..

but we know that momentum is equal to mv

comparing we get de-broglie wavelength.

Answer 2

★☆〖Qบęຮτ ı¨ ø nˇ〗☆★

⭐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:

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