  1. Identifying Converging and Diverging Lenses: Explaining with …

    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 …

  2. Air Bubble in Water: Converging or Diverging Lens?

    Dec 12, 2011 · The discussion centers around the optical properties of an air bubble in water, specifically whether it behaves as a converging or diverging lens. Participants explore the …

  3. 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 …

  4. 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 …

  5. 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 …

  6. 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 …

  7. 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 …

  8. 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 …

  9. Focal Length - please check my work and tell me what's wrong.

    Apr 8, 2010 · A converging lens with a focal length of 11.4 cm is 30.0cm to the right of the diverging lens. The two-lens system forms a real inverted image 17.0 cm to the right of the …

  10. 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. …
