Objects appear upside down when viewed using a microscope due to the fact that many microscopes use multiple lenses; this causes rays of light to cross, which results in an inverted object. A microscope that utilizes multiple lenses is known as a compound microscope. When using a compound microscope, users must remember that the slide is being viewed upside down and back-to-front.Know More
When the scientist moves the slide to the left, it will appear to move to the right when viewed using the microscope.
When novice users practice utilizing the microscope, it is best to keep both eyes open rather than shutting the eye that is not peering through the lens. This practice helps prevent eye strain.Learn more in Optics & Waves
In 1886, Heinrich Hertz demonstrated that radio waves that hit objects are reflected, and in 1897, the first accidental radar detection of a ship was performed by Alexander Popov. In 1904, Christian Hulsmeyer made a practical demonstration of intentional detection of metallic objects using a radar.Full Answer >
A compound microscope can be used to observe or analyze microscopic objects or organisms that may otherwise be too small for the naked human eye to accurately observe. Compound microscopes differ from common light microscopes and stereoscopes in their design and overall function.Full Answer >
A light microscope can use multiple types of light to produce multiple types of images, but all of them function on the basis of light focused from below the sample and into either a condenser, which focuses the light, or the lens to be viewed. The objective lens are what causes the actual magnification of the specimen on the slide that is made visible by the light. That is then passed through to the eyepiece at the top of the microscope.Full Answer >
The dual nature of light refers to the fact that light can act as both a wave and a particle. Albert Einstein's photoelectric effect experiment proves that light can behave as a particle while Thomas Young's double-slit experiment shows that it also behaves as a wave.Full Answer >
