Question
The energy of a photon of light with wavelength 5000
is approximately 2.5 eV. This way the energy of an X-ray photon with wavelngth 1 would be
is approximately 2.5 eV. This way the energy of an X-ray photon with wavelngth 1 would beOptions
A.
B.2.5 × 5000eV
C.
D.
Solution
Energy of photon
E =
⇒ 2.5 eV =
(asλ = 5000 )
⇒ hc = 2.5 × 5 × 10-7eV
For X-ray photon,C =same,h = constant
⇒ E =
=
eV
= 2.5 × 5000eV
E =
⇒ 2.5 eV =
(asλ = 5000 )⇒ hc = 2.5 × 5 × 10-7eV
For X-ray photon,C =same,h = constant
⇒ E =
=
eV= 2.5 × 5000eV
