________ are formed when an opaque objects comes in the path of light. 

The correct answer is Shadows.

Key Points

• Shadows:-
  • These are formed when opaque objects come in the path of light. When light rays hit an opaque object, they are either absorbed or reflected, preventing them from reaching the surface behind the object.
  • As a result, a shadow is cast on the surface opposite to the light source, creating a darker area.
  • Shadows provide valuable information about the position, size, and shape of objects, and they play an essential role in various fields such as art, photography, physics, and astronomy.

Additional Information

•  Mirror reflections:-
  • It occur when light hits a smooth, reflective surface, such as a mirror, and bounces back in a predictable manner.
  • The law of reflection governs this phenomenon, stating that the incident angle (the angle between the incoming light ray and the normal, a line perpendicular to the mirror's surface) is equal to the reflected angle (the angle between the outgoing light ray and the normal).
• Transparent rays:-
  • It refers to rays of light that pass through a material without being absorbed or scattered significantly.
  • Transparent materials allow light to pass through them in a straight line, maintaining the direction and intensity of the light rays.
  • When you look through a transparent material, objects on the other side are clearly visible and not blurred, as the light rays do not get scattered or diffused.
