Image formation by concave mirror

To understand the image of an object formed by a concave mirror, learn example problems and solutions below. In this problem the object is assumed at a certain distance from the concave mirror, then draw the image formation by the concave mirror, the image distance from the concave mirror and the magnification of the image …

Ray diagrams for concave mirror

If an object is in front of a concave mirror that reflecting light, the concave mirror will form the image of the object. If the position of the object in front of the concave mirror is known, how to draw the image formation of the object? To clarify this, suppose an object is in front …

Concave mirror

Definition of a concave mirror One type of mirror used in everyday life is a concave mirror. A concave mirror is a curved shape mirror, where a mirror surface reflects light curves backward. Uses of the concave mirror If you want to observe your facial skin more clearly and in detail, close your face to …

Plane mirror

Definition of the plane mirror A plane mirror is a mirror that has a flat surface, where one of its surfaces is coated with reflective metal so that the surface of the plane mirror can reflect more than 95 percent of the light that strikes it. If you shine a flashlight toward a plane mirror …

Law of reflection of light

Definition of reflection Reflection can be interpreted as an event in which the direction of motion of an object changes due to the object hits a barrier. If you throw a ball on the wall, the ball reflected because the ball hits the wall. Reflection of light When light is emitted by the sun or …

Poiseuille’s equation

Poiseuille equation was discovered by Jean Louis Marie Poiseuille (1799-1869). As explained, each fluid can be considered as an ideal fluid. The ideal fluid does not have viscosity. If we assume an ideal fluid flows in a pipe, each part of the fluid moves at the same rate (v). Unlike the ideal fluid, the real …

Viscosity

Fluid, both liquid and gas substances of different types have different viscosity levels. Viscosity is a friction between the molecules that make up a fluid. So the molecules make up fluid friction when the fluid flows. In liquids, the viscosity is caused by cohesion forces (pulling forces between similar molecules). Whereas in gas substances, the …

Capillarity

Force of Cohesion and Adhesion Cohesion force is an attraction force between molecules in a similar substance, while an attraction force between molecules of an unequal substance is called the Adhesion Force. For example, we pour water into a glass. Cohesion occurs when water molecules attract each other, while adhesion occurs when water molecules and …
