draw a diagram to show when an object is at infinity and mention its properties also
Answers
Explanation:
Convex Mirror :
When the object is at the infinity, a point sized image is formed at principal focus behind the convex mirror.
Properties of image: Image is highly diminished, virtual and erect.
Convex Lens :
Convex lens converge parallel rays coming from objet at infinity and a highly diminished - point sized, real and inverted image is formed at principal focus F₂.
Properties of Image: Image is highly diminished, real and inverted.
Concave Mirror :
Since parallel rays coming from the object converge at principal focus, F of a concave mirror; after reflection. Hence, when the object is at infinity the image will form at F.
Properties of image: Point sized ,Highly diminished ,Real and inverted .
Concave Lens :
A highly diminished point sized, virtual and erect image is formed when object is at infinity by a concave lens at principal focus F1.
Properties of Image: Image is point sized, highly diminished, virtual and erect.
