Answer: E
 Characteristic curve is a graph showing the relationship between exposure and density for a specific film-screen system.

Answer: A
 Speed point is the exposure required to produce a density of 1.0 above the base plus fog level.

Answer: B
 Gamma is the slope of the characteristic curve.

Answer: F
 Latitude is the range of exposures over which acceptable radiographic densities can be obtained.

Answer: G
 Average gradient is the change in density per unit exposure at a specified point on the characteristic curve.

Answer: H
 Sensitometer is used to measure the speed and contrast of a film-screen system.
