MIRROR -The simplest and the most common optical instrument. -Uses the Law of Reflection to redirect light it receives. -It reflects most of the light in one direction. -Good reflecting mirrors can have 85% reflectance. Types of Mirror 1. Plane Mirror A mirror with a flat surface. Image formed: Laterally inverted Upright and always the same size as the object they reflect. Virtual image (images appear to behind the mirror) at the same distance as the object in front of the mirror. Examples:

The Moultrie Panoramic 150 Game Camera Review: The New Standard-Bearer in Trail Photography There has never been a camera that breathes such life into Trail Photography. Even now‚ field of view has been quite a limited feature of trail and wildlife cameras. With that said‚ I urge you to salute the Moultrie Panoramic 150. Flaunting a breath-taking 150-degree angle of view‚ it works alongside its 3 Passive Infrared (PIR) motion sensors to reshape trail photography in a way like never before. Sporting

In the Polaroid design the membrane is a special foil consisting of a Kempton® film coated with gold. The foil is stretched over a V-grooved plate‚ Figure 2.5. The transducer is protected by stainless steel housing. A few models with different housings are available. The sizes of these transducers are the main drawback since they are from 30 up to 45 mm in diameter. A further analysis of this structure and its dynamic features is found in [Attila et. al.‚ 1995]. The piezoelectric transducer is based

Refraction of light in water Refraction is the change in direction of a wave due to a change in its transmission medium. Due to change of medium‚ the phase velocity of the wave is changed but its frequency remains constant. This is most commonly observed when a wave passes from one medium to another at any angle other than 90° or 0°. Refraction of light is the most commonly observed phenomenon‚ When light travels from air into water‚ it slows down‚ causing it to change direction slightly. This

The microscope has been one of the greatest inventions in the history of science and has had the most impact on the course of science. Ever since the first microscope was invented in 1590‚ they have improved our knowledge in basic biology and biomedical research‚ as well as many other things‚ all of which are important. The smallest object a human can see with the naked eye is 0.2 mm‚ for example‚ algae cells. The light microscope‚ however‚ allows us to see things almost 1000 times smaller that what
