Question

Electrons with de broglie wavelength lambda falls on the target

Answer 1

Answer:

Explanation:

The kinetic energy of the incoming electron is:

T

=

p

2

2

m

=

(

h

λ

)

2

2

m

=

h

2

2

λ

2

m

Assuming that all of this energy is converted into a photon in the Bremsstrahlung process, that photon will have energy:

h

c

λ

o

=

h

2

2

λ

2

m

Or:

λ

0

=

2

m

c

λ

2

h

Most photons will have lower energies, which is why it is a cut off.
