Where should an object be placed in front of a convex lens so as to obtain its virtual, erect and magnified image? To obtain a virtual, erect, and magnified image of an object, it should be placed
within the focus , i.e., between the optical centre and the focus of a convex lens
.
Where should an object be placed in front of a convex lens to get magnification (- 1 of lens?
If the lens has a focal length of 20 cm, the object must be positioned
40 cm in front
of the lens, creating an inverted image of the same size as the target, 40 cm behind the lens. Magnification is -1 and hence the image size is same as object size.
Where should an object be placed in front of a convex lens to get a diminished real image?
Size of image is diminished. Therefore, a real object be placed in front of a convex lens
at infinity
to get real and diminished image of the object.
Where should an object be placed in front of a convex lens of focal length 0.12 meters?
Where should an object be placed in front of a convex lens of focal length 0.12 m to obtain a real image of size three times the size of the object, on the screen ? Ans.
0.16 m in front of lens
11.
Where should an object be placed in front of a concave?
Now, we know that the radius of curvature is twice the distance of the focal length from the mirror. Hence, the object must be placed at
the center of curvature
.
Where an object should be placed in front of a concave mirror to get a real image of the size of object?
Answer: The object should be placed
at the centre of curvature of the
concave mirror to obtain an image of same size and real image.
Can a convex lens produce a real image?
Plane mirrors, convex mirrors, and diverging lenses
can never produce a real image
. A concave mirror and a converging lens will only produce a real image if the object is located beyond the focal point (i.e., more than one focal length away). … The image of an object is found to be upright and reduced in size.
When an object is placed in front of a convex mirror?
The ray diagram above illustrates that the image of an object in front of a convex mirror will be located at a
position behind the convex mirror
. Furthermore, the image will be upright, reduced in size (smaller than the object), and virtual.
Where should an object be placed in front of a convex lens of focal length 10 cm?
Calculate the distance at which an object should be placed in front of a convex lens of focal length 10 cm to obtain a virtual image of double its size. Here, u=?,f=10cm,m=+2, as image is virtual. Therefore, object should be placed at
a distance of 5 cm from the lens
.
At what distance should an object be placed in front of a convex lens?
The object should be placed at a distance of
-72 cm
from the lens.
At what distance should an object be placed in front of a convex lens of focal length 0.4 m so that the virtual image is thrice the size of image?
What distance should an object be placed in front of a convex lens of focal length 0.4 m so that the image is thrice the size of the object ? Given, f=0. 4m,h-1=3h0,u=? That is, object distance
u = 0.267 m
.
Where should an object be placed in front of a concave mirror to obtain magnification of 3?
For the magnification value of -3, the image formed will be real, inverted and enlarged/magnified. The object must be placed
between the principal focus F and the centre of curvature C of the concave mirror
.
Where should the object be placed in front of a concave mirror to form a real and inverted image?
Where should an object be placed in front of a concave mirror to obtain an image, which is real, inverted and reduced in size? Solution : For real, inverted and reduced image, the object must be
placed beyond the centre of curvature
.
At what distance should an object be placed in front of a concave mirror of focal length 50 cm?
Therefore, the object is to be placed at distance
75 cm
from the mirror so that its image is two times magnified, real and inverted.
What type of image is formed when an object is placed in front of convex mirror?
Virtual images
are always formed by convex mirrors and are formed by concave mirrors when the object is placed in front of F.
Where an object must be placed in front of a concave mirror so as to form an image that is no image?
When the object
is located at the focal point
, no image is formed. As discussed earlier in Lesson 3, light rays from the same point on the object will reflect off the mirror and neither converge nor diverge.
