Answer:
Wavelength = 64.635 pm
Explanation:
The expression for the deBroglie wavelength and kinetic energy is:
Where,
is the deBroglie wavelength
h is Plank's constant having value
m is the mass of electron having value
K.E. is the kinetic energy of the electron.
Given, K.E. = 360 eV
Energy in eV can be converted to energy in J as:
1 eV = 1.6022 × 10⁻¹⁹ J
So, K.E. =
Applying in the equation as:
Also, 1 m = 10¹² pm
<u>So, Wavelength = 64.635 pm</u>
