Notes of Business Taxation   We are going to share with you the notes for different classes as mention above just for the help of our students, so that they can perform best in exams and in the near future, they can become good citizen of our society and take part in the development of…

How a Rainbow is formed   As we know a prism disperses sunlight into a series of seven colors. When rain falls, raindrops behave like a prism and white light entering the raindrop splits up into seven colors on refraction. These are appeared as Rainbow.   As for studying in Great Britain, there is one…

Max Plank Quantum Theory   According to this theory of Max Plank:   Light is emitted from a source discontinuously in the form of bundles of energy called Photons or Quantum.   It travels in space as well as a medium. Speed of light is greatest in space or vacuum.   Education in Australia Many…

Newton Corpuscular Theory of Light   This theory which was proposed by Newton is as follows:   Light is emitted from a luminous body in the form of tiny particles called corpuscles.   The corpuscles travel with the velocity of light.   When corpuscles strike the retina they make it sense light.   Medium is…

Islamiat Notes for Class 10 We are going to share with you the notes for different classes as mention above just for the help of our students, so that they can perform best in exams and in the near future, they can become good citizen of our society and take part in the development of…

Huygens Wave Theory of Light   In 1676, Huygens proposed this theory, According to this theory:   Light propagates in space in the form of waves.   It can travel in space as well as in a medium.   Light does not travel in a straight line but in sine wave form.   Velocity of…

Real image and Virtual image Physics   Real Image:   Real image is formed when rays after reflection actually meet at a point.   Real image is inverted and can be seen on a screen.   It has a physical existence. I     Virtual Image:   Virtual image is farmed when rays do not…

Lenses and its Types in Physics   Lenses A transparent and smooth glass or any refracting medium surrounded by two spherical surfaces is known as lens.   Types of Lenses   There are two types of lenses:   Convex Lens:   If the glass is thick at the center and thin at the edges then…

What is Prism in Physics   Prism is a transparent piece of glass. I t has three rectangular Sides and two triangular sides.   In addition, it is often expensive for students to study due to travel and other expenses during their studies. Even with a temporary connection to the Internet, you will be able…

Definition  of Snell’s Law   The refractive index between two particular mediums is equal to the ratio of speed of light in first medium and Speed of light in second medium equal to the ratio between sin <i and sin <r.     Refractive Index = sin<i/sin<r = Speed of light in first medium/Speed of…
