Question

Differentiate between the following
a) Image and Shadow
b) Real and Virtual Image
c) Luminous and Non-Luminous Objects

Answer 1

Explanation:

(. A). We know that an image is a picture of an object while shadow is formed an object comes in between the surface and light. ... The formation of image takes place when the light rays are reflected by an object. The formation of shadow takes place when the light falls on an opaque object.

(B).A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted.

(C) Objects that can emit light energy by themselves are known as luminous objects. Objects that cannot emit light energy by themselves are known as non-luminous objects. These objects can cause a sensation of light. These objects do not cause the sensation of light.
