Identifying Converging and Diverging Lenses: Explaining with Principal ...
Feb 1, 2005 · To determine whether a lens is converging or diverging, analyze the behavior of the principal rays after they pass through the lens. A convex lens will cause rays to converge at a point …
Focal Length of Diverging Lens: Negative Value Confirmed?
Jun 18, 2007 · The focal length of a diverging lens is definitively always negative, as confirmed by optical conventions. This characteristic is fundamental to understanding lens behavior in optics. Diverging …
Is it possible to have a Mach number greater than 1 at the throat?
Mar 5, 2012 · The discussion centers around the possibility of achieving a Mach number greater than 1 at the throat of a converging-diverging nozzle in gas dynamics. Participants explore theoretical …
Is there a pressure ratio limit for choked flow through a c-d nozzle ...
Jun 21, 2024 · The discussion revolves around the conditions for achieving choked flow through a converging-diverging (c-d) nozzle, specifically examining the effects of diameter and angle of the …
What is the image height formed by the new diverging lens?
Mar 28, 2010 · The discussion focuses on calculating the image height formed by a diverging lens when an object is placed 27.5 cm from it. The object height is given as 5.00 cm, and the focal length of the …
Why Do Diverging Lenses Always Produce Shrunken Images?
Apr 24, 2010 · Diverging lenses consistently produce shrunken and inverted images regardless of the object's position relative to the lens. This phenomenon occurs due to the geometric properties of light …
Focal Length - please check my work and tell me what's wrong.
Apr 8, 2010 · The discussion revolves around a two-lens system involving a diverging lens and a converging lens. The original poster presents a problem where a small object is positioned 25.0 cm …
What is the magnification problem with two lenses?
Oct 25, 2006 · The problem involves two lenses positioned 38 cm apart, where one lens is diverging with a focal length of -7 cm and the other is converging with a focal length of 16 cm. Participants are …
Real Object, Images formed by a single converging or diverging lens ...
Mar 31, 2010 · Homework Statement Starting with a real object, which of the following statements are TRUE about the image formed by a single lens? (Choose ALL correct answers, e.g. B, AC, CDF.) A) …
How to determine when compressible flow is choked?
Jun 9, 2024 · Others argue that adding a diverging section after the throat allows for a lower upstream to downstream pressure ratio while still achieving choked flow, which seems counterintuitive. It is …
