1

General properties of x-rays (7)

Shorter wavelength than light waves
Can penetrate more deeply
Able to pass through vacuum
Travel in straight lines
Interact w/matter through absorption or scatter
Fluorescent
Darkening effect on film

2

Type of radiation

Electromagnetic

3

Brief description of how x-rays produced

When electrons travelling at high speeds strike matter
Collide with other atoms & lose their kinetic energy
Transformed into heat (99%) and x-rays (1%)

4

Define thermionic emission

Applied heat energy causes atoms to vibrate
Binding energy of atoms breaks down
Free electrons released

5

How does thermionic emission occur

When current applied to filament causing it to heat up and release electrons

6

Define electron transmission

When high voltage applied across cathode and anode
Electrons accelerated across vacuum toward target

7

What does voltage affect (3)

Speed of electrons
Energy of produced x-rays
Penetrative power of x-rays

8

What does current affect (2)

Number of electrons released
Number of x-rays produced
