Answer» i) The image on the white drawing sheet is inverted. ii) I notice that the image formed through the magnifying lens is clearer than that formed with a pinhole camera. iii) Similarity: Shadow and image are related to light. Without light both are not visible. Difference: The key difference between image and shadow is that the image is the reflection of the light rays by an object, whereas the shadow is a dark shape projected onto a surface when an opaque object obstruct the light rays. The term image generally refers to an optical representation of a real object. A shadow is black in color while an image is colorful, and represents the real colors of the object it represents. |
