Properties of light:
The wavefronts can be of different shapes depending on the size and shape of light source and the distance from it. Huygens' principle states that every point on a wavefront behaves as the source of small secondary wavelets which spread out in all directions with a velocity equal to the velocity of light. The new wavefront is then found by constructing a surface of envelope tangential to the secondary wavelets.
Applying Huygens' principle, the phenomenon of reflection and refraction could be explained. The velocity of water waves depend on the depth of the water. The principle of superposition of waves states that when two or more waves travel through the same portion of a medium simultaneously, the resultant displacement at any point is the vector sum of the displacements due to the individual waves.
How many times the kinetic energy reach at minimum and maximum point during one oscillation?
Q. Why does heat makes matter to expand? Answer:- Water contracts as it cools similar to all other liquids until it reaches a temperature of about 4 degrees Celsius at whi
Semiconductor is solid material whose electrical conductivity at room temperature lies between conductivity of a conductor and that of an insulator. At high temperatures its conduc
Are fibers safe? Fiber optics are passive components, hence do not use power to generate light, like the case with lamps. When light conductors only carry light from one point
