| xrays make radiographic film _____ (color) | |
| visible difference between two adjacent radiographic densities | |
| hihg frequency type _______ are used in clinics to allow thousands of electrical waves to flow towards the xray tube instead of standard 60 cycle US alternating current | |
| thicker parts absorb (more/less) xrays and make film (darker/lighter) | |
| a ______ transformer reduces incoming line current from amperes down to mA, called the 'low voltage' circuit | |
| xrays are a form of __________; which are bundles of energy that travel in waves | |

| part of xray machine that directs electrons towards the light | |
| Stationary base is made of what metal? | |
| (small/large) focal spots are desired because they result in very clear images | |
| The _____ effect is where the intensity of the beam varies and is stronger on the cathode side due to the angle of the target | |
