Shadows if an opaque comes in the path of light rays Arctic region phone behind the objects is due to the reason that light rays cannot pass through the Opaque object that is Indus form is called said all the copy object the place where light has not reached at all is completely dark.images when will look into million BC our face what we see in the mirror is regular reflection of our face and it is called make any two production of physical object formed by reflection in mirror is called image.

Shadow:

A shadow is a dark area or shape that is formed when an object blocks the path of light. It is essentially the absence of light due to the obstruction created by an object. Shadows are formed when light rays are blocked by an opaque or translucent object, preventing them from reaching a particular area.

Formation of Shadows:

Shadows are created when light travels in a straight line and encounters an obstacle. The shadow is formed on the opposite side of the object, away from the light source. The size and shape of a shadow depend on the angle and intensity of the light source, the size and shape of the object casting the shadow, and the distance between the object and the surface where the shadow is cast.

Properties of Shadows:

Shadows possess several distinct properties that help us understand their nature and behavior:

1. Shape: Shadows generally have the same shape as the object casting them, although they may appear distorted depending on the angle of the light source and the surface on which the shadow falls.

2. Size: The size of a shadow is determined by the relative distances between the object, the light source, and the surface where the shadow is cast. The farther the object is from the surface, the larger the shadow will be.

3. Intensity: Shadows can vary in intensity, ranging from a sharp, well-defined outline to a soft, diffused edge. This depends on the size and shape of the light source and the transparency of the object casting the shadow.

Image:

An image refers to a visual representation or depiction of an object formed by the interaction of light with a surface. When light rays reflect off an object and enter our eyes or a camera lens, they form an image of the object on the retina or the camera sensor respectively.

Formation of Images:

Images are formed through a process of reflection or refraction. When light rays bounce off a smooth surface, such as a mirror, the image formed is a reflection of the object. On the other hand, when light passes through a lens or bends as it enters a different medium, such as water, the image formed is a refraction of the object.

Properties of Images:

Images possess certain characteristics that help us understand how they are formed and perceived:

1. Orientation: The orientation of an image can be either upright or inverted, depending on the type of reflection or refraction that occurs. Mirrors generally produce upright images, while lenses can create both upright and inverted images.

2. Size: The size of an image is determined by the distance between the object and the surface on which the image is formed. It can be magnified or reduced compared to the actual object depending on this distance.

3. Clarity: The clarity or sharpness of an image depends on the quality of the reflecting or refracting surface. A smooth, undistorted surface will result in a clear image, while a rough or irregular surface may cause distortion or blurring.

In summary, shadows are the dark areas formed when light is obstructed by an object, while images are visual representations formed through reflection or refraction of light. Both shadows and images play crucial roles in our perception of the physical world and have distinct properties that make them fascinating phenomena to study.
