min dark room size is __ by __ feet | |
number of protons is (greater, equal, less) number of electrons | |
_____ wavelengths have higher frequencies | |
The _____ effect is where the intensity of the beam varies and is stronger on the cathode side due to the angle of the target | |
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 | |
