Introduction:  

Objects are of different types, such as transparent, translucent, and opaque. This classification of objects has been done by their ability to be see through. Transparent objects are completely see-through. Whereas opaque objects are not at all see-through. However, the translucent objects are partially see-through.  

Explanation: 

Shadows: 

Opaque objects block light falling on them, which leaves a dark area behind them, called the shadow.  

Opaque objects forming a dark shadow 

Opaque objects form the darkest shadow, as they block most light that falls on them. Translucent objects such as sunglasses, oil paper, tinted glass, colored plastics, etc., form a lighter shadow as they block some light that falls on them and let the rest pass through.
