## 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...

## 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...

## 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...

## 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...

## Specular reflection and diffuse reflection

If you stand in front of a plane mirror, you can see the image of your face reflected by the plane mirror. If you stand on the edge of a plane mirror, can you still see your face behind...

## 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...

## Wavefront, ray, beam of light

Definition of wavefront If you throw a stone into a pool of water, circular water waves moving away from the center of the circle. In the water waves, there are crests and troughs. Wave peaks or waves valleys that...

## 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...

## 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...

## 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...
