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 about 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 >
Translucent materials allow light to pass through them, but they diffuse the light in a way that make objects on the opposite side appear blurred. Examples of translucent materials are frosted glass, oil paper, some plastics, ice and tissue paper.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 >
A microscope is an instrument that magnifies objects, enabling visibility of 1,000 times or more than what can be seen by the naked human eye. Microscopes of various types assist researchers with medical diagnostics, and they have aided scientists in attaining knowledge of biology and material science.Full Answer >
