1. Draw a concave lens with the principal axis. 2. Mark the optical center and the focal points (F and 2F). 3. Place the object 15 cm to the left of the lens. 4. Draw a ray parallel to the principal axis that d
To solve the problem, we will follow these steps:Step 1: Identify the Given Values - Height of the object (h) = 5 cm - Focal length of the convex lens (f) = +50 cm (positive because it's a convex lens) - Object distance (u) = -
deflector and a principal ray of a scanning beam from the deflector to a scanned surface travel on the opposite sides of an optical axis of an optical element(s) wherein entrance and exit surfaces of the optical element(s) are both concave toward the deflector in the sub-scanning section....
