Electric Field Lines A line drawn in electric field such that tangent to the line at point on it gives the direction of electric field at that point, is called electric field line. (i) Electric field lines emerge form a positive charge and terminate into a negative charge.i.e.Electric lines of force usually start or diverge … Read more

In geometrical optics we analyze the formation of images by assuming the light to travel in a straight line path or rays. For this reason geometrical optics is also known as ray optics. Ray of Light: A ray of light gives the direction of propagation of light. When light meets a surface, which separates the … Read more
