Convex Lens & Concave Lens
Real image and virtual image Looking at an object, we feel there is an object in it. By the way, if you feel that there is something, we say there is an ‘image,’ even if there … more

Precipitation Reaction
A precipitation reaction is a type of reaction when two solutions react to form an insoluble solid (ionic salt) A lot of ionic compounds dissolve in water and exist as individual ions. But when two ions … more
Refraction on water
Refraction is the bending of a wave caused by a change in its speed as it moves from one medium to another. This occurs because of the slow speed of light in dense materials. Examples of … more
Equilibrium
* If the simulation does not move, please refresh the web page. Radiation Places near the stove feel warmer than far away. This is due to the direct transfer of heat from the stove without the … more
Phase array
Spinning radar In general, electromagnetic waves (radio waves) propagate in all directions. In this case, radio waves can be transmitted or received in any direction. However, as the distance increases, the strength of the radio wave … more
Plants Respiration
Plants Respiration Animals carry out active breathing movements to obtain the energy they need for life activities. Through this breathing movement, oxygen is absorbed, and carbon dioxide is released. Like animals, plants do respiration. However, plant … more
Newtonian Reflector
Refracting telescope A telescope that uses only the refraction of a lens is called a refracting telescope. There are two types of refracting telescopes depending on the combination of lenses. The Galilean telescope is often referred … more

Solar System
Solar System All the orb bodies that revolve around the sun and their space are called the solar system. The celestial bodies that make up the solar system include the eight planets revolving around the sun … more
Kinetic Energy
Kinetic energy All moving objects have kinetic energy. The kinetic energy Ek of an object with a mass of ‘m’ and a velocity of ‘v’ can be calculated as follows. \[E_{ k }=\frac { 1 }{ … more
