The law of conservation of electric charges

Every material in the universe is composed of atoms. Atoms are composed of protons, neutrons, and electrons. Proton is positive electrically charged; electron is negative electrically charged, neutrons are not electrically charged. Inside the atom, there are some electrons,...

Types of electric charges

Why does plastic repels plastic but attract glass? If you rub a plastic on dry hair and bring the plastic to the small pieces of paper, the plastic pulls the pieces of paper. Why can plastic also pull pieces...

Electric charge

Please observe one of the objects that are around you. If you destroy an object, for example, it is a stone, the stone will be divided into smaller pieces. If the part of the stone is destroyed again, the...

Optical instrument camera

Parts of camera A simple camera consists of a convex lens, diaphragm, shutter, and film. Convex lenses function to form the real and inverted image on the film. Unlike the lens of the eye that has a focal length...

Equation of astronomical telescope

Angle determines the size of an image of the object formed on the retina. As shown in the figure, the farther the object distance from the eye the smaller the angle and therefore the smaller the image size formed...

Astronomical telescope

Definition of the astronomical telescope Astronomical telescopes or astronomical binoculars are the optical instruments used to help the eye see celestial objects such as stars, planets, satellites, etc. Although the size of celestial objects is huge the distance of...

Equation of microscope

Angle determines the size of the image of the object formed on the retina of the eye. As shown in the figure on the side, the smaller the size of the object, the lower the angle and hence the...

Microscope

Definition of microscope A microscope is an optical instrument used to help the eye see very small objects, where the tiny objects are difficult to observe directly using eyes or loupe. There are two types of the microscopes namely...

Equation of loupe (magnifying glass)

As explained in the topic loupe (magnifying glass), an object appears small when viewed from a great distance and looks great when viewed at close range. The difference in the size of the object seen by the eye is...

Loupe (magnifying glass)

Definition of magnifying glass A loupe or magnifying glass is a convex lens that is used to help the eye see an object that is difficult to observe directly using the eye. The loupe is called a simple magnifier...
