Refraction of Light Through Spherical Surfaces

Refraction:  The bending of light when it travels from one medium to a different is referred to as Refraction. Usually, when gentle travels from a denser medium to a rarer medium, the sunshine modifications its course and strikes away from the traditional and whereas travelling from a lighter medium to a denser medium it shifts its… Continue reading Refraction of Light Through Spherical Surfaces

Electric Motor

Electric Motor The electric motor is an important indicator of industrial progress. It is a very simple and very useful machine. An electric motor is a machine by which electrical energy is converted into mechanical energy. It was invented in 1822AD by the British scientist Michael Faraday. The first commutative DC motor capable of driving… Continue reading Electric Motor

Functions of the Eye

The functions of the eye constantly adjust the amount of light, focuses on objects near and far, and produce continuous images that are instantly transmitted to the brain. Focused by the cornea and the crystalline lens, the light makes its way to the retina. The eye’s retina contains millions of tiny light-sensing photoreceptor nerve cells… Continue reading Functions of the Eye

Visual Impairments

Visual Impairments or Defects of Vision The conditions when the eye’s adjustment capacity becomes weak, then the objects do not appear clear is called visual impairments. In these cases, the reflection of the object does not form an image on the retina, but rather in the front or back. This condition is called Visual Impairments… Continue reading Visual Impairments

Magnetic Effect of Electric Current

Magnetic effect of electric current A magnetic field is generated around an electric current in a conductive material, this phenomenon is called the magnetic effect of electric current. The Experiment of Oerested’s: To confirm the magnetic effect of the electric current, Oersted did the following experiment: Oersted installed a copper current-carrying circuit near a compass… Continue reading Magnetic Effect of Electric Current
