What type of image is formed by the concave side of the spoon?
On the other hand, the concave side of the spoon acts like a concave mirror. If the spoon is held at arm’s length, the object (you) is farther from the reflecting surface than the center of curvature. As a result, a real image is formed that is inverted and reduced in size with respect to the object.
In which case the image formed by convex lens is virtual?
Virtual images are always upright and cannot be projected. Virtual images are larger than the object only in case 2, where a convex lens is used. The virtual image produced by a concave lens is always smaller than the object—a case 3 image.
Which of the following best describes images formed by a plane mirror?
Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object’s distance, and the same size as the object.so,A virtual image is formed behind the mirror best describes image formation by a plane mirror.
What is the size of image formed by convex mirror?
The size of the image formed by the convex mirror is always smaller than the size of the object irrespective of the position of the object.
Can we place an object at the focus of a convex mirror?
No image will be formed.
What are the six cases of convex mirror?
To summarise
| Position of the object | Position of the image | Size of the image |
|---|---|---|
| At infinity | At the focus F, behind the mirror | Highly diminished, point-sized |
| Between infinity and the pole P of the mirror | Between P and F, behind the mirror | Diminished |
What is the focal length of a concave mirror?
Focal Length – The distance between the pole P of the concave mirror and the focus F is the focal length of the concave mirror. Thus, the focal length of a concave mirror can be estimated by obtaining a ‘Real image’ of a distant object at its focus, as shown in the figure.
Can you determine the focal length of the concave mirror if u is less than F?
Answer. no. we can’t calculate.
How can we find the rough focal length of a concave mirror?
Arrange your mirror, meter stick, and screen. Point the mirror at distant (greater than 10 m) object and move the screen along the meter stick until you obtain a sharp image of the distant object on the screen. The distance between the mirror and the screen is the approximate focal length of the mirror.
How do you find the focal length of a concave mirror with UV?
Calculate the focal length of the given concave mirror by using the relation, f = uv/(u+v). Repeat the experiment for different values of u (up to 2.5f) and in each time, measure v and record it in the tabular column.
Which method is used to calculate the focal length of a concave mirror?
