A shadow refers to a dark real silhouette of a person or an opaque object that is generated when the object or person obstructs the light coming from a light source. As we know, the length of the shadow is proportional to the cotangent of the angle of elevation, we can say that. (b) translucent Light does not bend its path of propagation if the size of the obstructing object is not comparable to the wavelength of light. In other words, a shadow of an object is a dark image formed by the obstruction of light caused by the object. the contrast between the shadow and the surrounding area is much more and therefore, we can clearly see the shadow formation.
