RT 111

Question 1

Explain Anode Heat

Answer 1

1. projectile e interact w/ outer shell e
2. low energy = NOT ionize, but excited
3. excited outer shell e releases heat/infrared
4. e returns to og state

Question 2

Explain Characteristic Radiation

Answer 2

1. projectile e interact w/ inner shell
2. inner shell ionize = e void
3. outer shell e fill vacancy
4. transition of outer to inner = charac x-rays

*low energy = orbital e fill is far from void
*high energy =orbital e fill is near void

Question 3

Explain Bremsstrahlung Radiation

Answer 3

1. projectile e miss orbital e, interact w/ nuclear field
2. projectile e is slowed down & change direction
3. slowed down fx = brems

*low energy =pe barely influenced by nuclear field (deflection =far)
*high energy =pe highly influenced (deflection =close to nucleus)
