Dip of the Prism

The dip of a prism refers to the angle between its original base plane and the true horizontal plane when the prism is placed in an inclined position. Essentially, it measures how much the prism is tilted or inclined from a level horizontal position. This concept is important in optical and surveying applications, where precise orientation affects measurements and observations. By determining the dip, one can understand the prism's orientation relative to level ground, which is critical for accurate data collection and alignment in various technical and engineering contexts.
