Which mirror show virtual image of object placed in front of it?
Plane Mirror And Other Spherical Mirrors Bulged Outside, Such As Convex Mirrors
What kind of image is created when an object is placed in front of a plane mirror?
A virtual erect image of the same size of the object is formed.
An object is kept in front of a concave mirror of focal length 20cm the image is 3 times the size of the object calculate 2 possible diastances of the object from the mirror?
40cm
Focal length of a concave mirror?
1/object distance + 1/ image distance = 1/focal length
What shape is a concave mirror and what do things look like in it?
A concave mirror bulges away from the incident light. The image of an object depends on where exactly the object is placed - relative the to focal length of the mirror. See the attached link for more details.
Where must an object to be located for a converging mirror to produce a virtual image?
if the focal length is greater than the object distance from the lens
Where must an object be located for a converging mirror to produce a virtual image?
if the focal length is greater than the object distance from the lens
In the distance from a converging lens to the object?
c virtual,upright,and larger than the object.
Where is the only location where a converging mirror will not produce an image?
When the object lies within its focal length then no real image can be produced
If the distance from a converging lens to the object is less than the focal length of the lens what willl the image appear to be?
C: virtual, upright, and larger than the object
Is a magnifying glass a converging lens or a diverging lens?
A converging lens is a simple magnifying glass when the object is within one focal length of the lens. The image is then virtual, magnified, and right-side up.
Is the image from a converging lens real or virtual?
If the object is more distant from the lens than the focal length of the lens, a real image is formed.
What is the focal length of a converging lens which produces a virtual image four time the size of the object the image being 15 cm from the lens?

How can a concave mirror produce a virtual image?
Virtual or real image... concave mirrors can form either virtual images or real images... i hope the answer would help you :)) Place the object closer to the mirror than its focal length.
How is virtual image formed in plane mirror?
When an object is illuminated, light rays scatter off it in all directions. Any rays that strike a flat mirror will reflect, but continue to diverge in a disorganized way. If some of these rays enter a human eye, the lens/cornea will stop them diverging and start them converging. This focusing process ensures that all rays emanating from a single point on the object arrive at a single point on the retina. However, the brain makes no allowance for the change of direction at the mirror and perceives the rays to have originated from an object behind the mirror. This apparent object is is called the virtual image of the mirror. It can only be viewed with the help of a converging lens, such as that in the eye, which forms a real image on the retina.
If an object is closer to a convex lens than one focal length the image is .?
If an object lies within the focal length of a convex lens, its image will be erect, bigger in size and virtual. It will be on the same side of the object.
Which mirror can produce virtual image larger than the object?
A concave mirror.
