If a human figure is standing in front of a concave mirror then his/her reflection will be like:
A taller n thinner
B shorter n flatter
C taller n flatter
D shorter n thinner
Answers
Answer:
(i) Image formed will be between the focus and center of curvature, it would be inverted and smaller in size as apparent from the ray diagram.
(ii) If the lower half of the mirror's reflecting surface is painted black, the position of image will be same but its intensity gets reduced.
Answer:
The correct answer is Option (A) Taller and thinner
Explanation:
The image would be upside down, would look as tall as the person, and would be at the same distance from the mirror as you are.
When a person stares at a concave mirror, the picture on a convex mirror is always virtual (rays do not flow through the image; their extensions do, as in a conventional mirror), decreased (smaller), and upright (not inverted).
- The picture grows larger as the thing approaches the mirror until it reaches roughly the size of the object when it hits the mirror.
- As the item goes away, the image shrinks in size and gets closer to the focus, until it is condensed to a point in the focus when the object is infinitely far away. Convex mirrors are highly useful in these situations because of these structures.
