Explain the Diagramming Waves?
There are two ways that waves can be indicated in a two-dimensional diagram. Parallel lines can be drawn that are meant to show the position of the peak displacement of the waves. This method is most commonly used to show water and sound waves, but it also is used for light, especially when we start talking about interference and diffraction.
Alternatively, rays may be drawn perpendicular to these wavefronts, indicating the direction of travel of the waves. Reflection of waves from a flat surface requires that the angle of incidence, θi (measured from the incoming ray to the normal of the reflective surface) must equal the angle of reflection, θr (measured from the normal to the reflected ray).
The color of sky is blue but the wavelenght of violet and indigo is small than that of blue.Then why the color of sky is blue? Ans) The particles in the atmosphere are able to
Mass energy relation - The total energy of a body is the sum of its kinetic energy and rest mass energy. Particle having rest mass zero always move with the velocity of light.
