what do you mean by "light rod" (acoustic rod?). do tou see a relationship with "wavelenghth"?
thanks

Hi ChrisChris Hillman said:Hi, Bernhard,
You don't by any chance mean "optical black hole" and "acoustic black hole", do you? http://relativity.livingreviews.org/Articles/lrr-2005-12/index.html

Jheriko said:Perhaps a light rod is a massless and perfectly rigid rod? Such constructs are sometimes used in the context of filling space with some coordinate grid. Since they are massless and perfectly rigid they do not interact or move, which is useful for a thought experiment.
A light rod, also known as an acoustic rod, is a device used in scientific experiments to study the properties of light and sound. It is typically a long, thin, and rigid rod made of a material such as glass or metal.
A light rod works by reflecting or transmitting light and sound waves along its length. It can be used to measure the speed of light and sound, as well as study their properties such as refraction and diffraction.
Light rods have various applications, including in spectroscopy, interferometry, and acoustic resonance experiments. They can also be used in the development of new technologies such as fiber optic communication and medical imaging.
Yes, a light rod can be used to bend light through the process of refraction. This occurs when light travels through a medium with a different optical density, causing it to change direction.
While the terms are often used interchangeably, there is a slight difference between a light rod and an acoustic rod. A light rod is specifically designed to study the properties of light, while an acoustic rod is used for studying sound waves. However, both types of rods function in a similar manner and can be used in a variety of experiments.
