An object should be placed
within the focus (between the pole and the focus)
and in front of the concave mirror to obtain a virtual, erect and magnified image. A concave mirror is a mirror that is curved inward in the middle.
Where should an object be placed in front of a concave lens to obtain image of the size of the object?
Answer: At
twice the focal length
, the image formed by the convex lens is real and of the same size as the object. 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.
Where should an object be placed in front of a concave lens to get a virtual and erect point sized image of the size of the object?
Answer: Correct option (d)
between the pole of the mirror and its principal focus
. The image formed by a concave mirror will be virtual, erect and magnified when the object is placed only between the pole and the principal focus of the mirror.
Where should an object be placed in front of concave mirror to obtain an image which is real inverted and reduced in size?
For real, inverted and reduced image, the object must be placed
beyond the centre of curvature
. A concave mirror produces three times magnified real image of an object placed at 10 cm in front of it.
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
.
At which position will you keep an object in front of a convex lens so as to obtain a point image?
When an object is placed at
the centre of curvature 2F
1
of a convex lens, we will get a real image of the same size as the object.
Where would you place an object in front of a concave mirror to produce a a real magnified image?
In E, the object is located in
front of the focal point
of a concave mirror. At such an object location, the image would be virtual, upright, and magnified. In F, the object is located between the center of curvature and the focal point of a concave mirror; the image would be real, inverted, and magnified.
Where should the object be placed in front of a concave mirror to form a virtual and magnified image?
An object should be placed
within the focus (between the pole and the focus)
and in front of the concave mirror to obtain a virtual, erect and magnified image.
What kind of image is created by a concave lens?
Concave lenses create only
virtual images
. After the rays are refracted, they never converge and so there will be no real images. All concave lens images will be upright, virtual, and diminished, and can be found between the F and the lens.
Where should an object be placed in front of concave mirror to get virtual erect and smaller than object?
when an object is placed in front of concave mirror, when object is placed at infinity : real image is formed
at focus of concave mirror
. size of image is much smaller than that of object.
At what distance should an object be placed in front of a concave mirror of focal length 20cm?
Answer Expert Verified
so the object must be placed
30 cm
from the mirror.
Where must an object be located in order for a concave mirror to form a real image?
Concave Mirror: Object Located At C
The object is located
at the centre of curvature (C) of the mirror
. The image is the same size, inverted and on the same side of the mirror between C and F. It is a real image.
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.
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 an object be placed in front of a concave mirror of focal length f?
it should be placed in
front of the focus itself
.
How many positions are there to keep an object in front of convex lens?
There are
six
possibilities of position of object in the case of convex lens: Object at infinity.
