  • Scalars and Vectors

    Introduction Vector and scalar quantities both are the physical quantity. The first one has both direction and magnitude but the latter one has only magnitude and no direction. The physical quantities are often used as physical terms like work, velocity, and force. They are classified into two quantities of Vector and scalar. Definition of Scalar…

  • Triangle Law of Vector Addition

    Introduction The Triangle Law of Vector Addition is the concept that is utilized to add the 2 vectors and is also determined as the method of head-to-tail. This law also helps to calculate the velocity, net displacement, and acceleration. The law helps in vector algebra in order to find the resultant of the sum of…

  • Scalar Product

    Introduction The scalar products are essential in order to understand the motion of vector quantities in real-time. These products can be subtracted or added at the same time with a proper algebraic formula for understanding the scalar quantity of different objects. These types of products are commonly denoted as the inner products or dot products…

  • Scalar and Vector Products

    Introduction The numbers or magnitude can measure a scalar product whereas the vector products are described with the direction along with the magnitude. A scalar and two vectors can be multiplied and can form two kinds of products according to the rules of physics. Both scalar and vector products are used for defining energy and…

  • Difference Between Scalar and Vector

    Introduction A vector and a scalar quantity can be explained with the help of algebraic principles. A scalar quantity represents a one-dimensional value whereas the vector quantity represents two and more than two-dimensional values. The motion of an object can also be represented with the help of a vector and a scalar quantity. What is…

  • Difference Between Real Image and Virtual Image

    Introduction In accordance with the laws of physics, for the production of an image, the rays of light, need to come from an object and meet at a particular point after being reflected and refracted. At the point where the rays meet, the image is formed. In the simple dictionary, anything that emits light rays…

  • Difference Between Diffraction and Interference

    Introduction In our day-to-day life we observe various phenomena like after the rain a rainbow is formed in the sky, splitting of white light into seven colors, and when water falls on petrol it also shows different colors. These all phenomena are related to the optical phenomenon of light. In this tutorial, we will discuss…

  • Brewster’s Law: Definition, Equation, Examples

    Introduction Brewster’s law is studied in optics. the science of light. If light waves could pass through all materials perfectly, you wouldn’t be able to see anything. All materials would turn invisible. On the other hand, if materials reflected all light perfectly, they would always appear white instead of coloured. Colours are visible only because materials…
