Where should an object be placed in front of a convex lens to get a real 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.
Where should an object be placed in front of a convex mirror to get a virtual image?
Object should be placed
between F and 2F
.
Where should an object be placed in front of a convex lens to get a real image of the size as the object draw the ray diagram for the same?
- the object should be kept at twice of focal length from the convex mirror to get an image of equal size.
- the image formed is real and inverted.
- refer to the attachment for the Ray diagram.
Where should an object be placed in front of a convex lens to get a real and diminished image of the object?
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 convex lens so that image formed is virtual and erect?
The object should be placed
between the optical centre and the focus of a convex lens
to obtain a virtual, erect and magnified image.
Why should we place an object in front of a concave mirror to get virtual image?
A concave mirror will only produce a virtual image if the object is located
in front of the focal point
. … Only a concave mirror can be used to produce an inverted image; and this only occurs if the object is located at a position of more than one focal length from the concave mirror.
Where is the object placed to get a same size of image and is inverted?
Answer: when the
object is placed at 2F1(twice the first focal length) in a convex lens
,then the image formed is a real, inverted and of same size….
Where should the object be placed so as to get a real?
Where should an object be placed so that a real and inverted image of the same size is obtained by a convex lens? The object should be placed
at a distance equal to twice the focal length of the lens
.
Where should an object be placed before a concave mirror?
▶▶So, the object must be placed
between Centre of Curvature and Focus at the distance of 30 cm from the mirror
.
Where will you keep an object in front of a concave mirror to get a real and diminished image?
Object is kept
between infinity and pole
Whenever the object is kept anywhere between the infinity and the pole of a convex mirror, then we get a diminished, virtual and erect image formed between the pole and focus behind the mirror.
What are the two uses of convex lens?
- A convex lens is employed in microscopes and magnifying glasses to converge all incoming light rays to a particular point. …
- The convex lens is used in cameras. …
- A convex lens is used for the correction of hyperopia. …
- The converging lens is used in the projector as well.
What type of lens would you use as a magnifying glass How close must the object be to the lens?
How close must the object be to the lens?
Convex lens
is a type of lens used as a magnifying glass. The object must be kept close, which will be within the focus of the lens (between the optical centre and the focus ).
Where should an object be placed in front of a convex lens of focal length 30 cm?
So, object is placed
at focus of concex lens
.
What type of image is formed by a convex mirror?
A convex mirror is a diverging mirror and forms only one type of image, namely
a virtual image
.
At what position should an object be placed in front of a concave mirror so as to get a real and inverted image of the same size 1?
Therefore, the correct option C i.e. the object should be placed
at the center of curvature of the
concave mirror so that image is the same size as the object.
What should an object be placed so that a real and inverted?
In case of convex lens when an object is placed at centre of curvature, a real, inverted and equal size
image
is obtained on the other centre of curvature.
