Is concave mirror real or virtual?
Concave mirrors can produce both real and virtual images depending on the distance from the mirror to the object and the curvature of the mirror, while convex mirrors produce only virtual images.
Can a concave mirror form a virtual image of the same size as the object?
no a concave mirror form a virtual image of same size as the object.
How does a concave mirror give a virtual image of an object?
Image formed by a convex mirror is always virtual and erect. When an object is placed at infinity, virtual image is formed at focus and the size of the image is smaller….Question 5.
| Concave mirror Image | Convex mirror image | |
|---|---|---|
| Position | Depends on the position of the object. | Always within the focus. |
What is difference between concave mirror and convex mirror?
Basically, the reflecting surface of convex mirror bulges outside while concave mirror’s bulges inwards. The major difference is the image that forms in these two mirrors. In other words, diminished images form in convex mirrors while enlarged images form in concave mirrors.
Why do concave mirrors form real images?
A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted.
Under what conditions can a concave mirror form real image of a virtual object?
With a concave mirror, the image is real if the object and the image are on the same side of the mirror i.e. the distance of the object from the mirror and the distance of the image from the mirror have the same sign.
How do you know if an image is real or virtual?
A real image occurs when light rays actually intersect at the image, and is inverted, or upside down. A virtual image occurs when light rays do not actually meet at the image. Instead, you “see” the image because your eye projects light rays backward. A virtual image is right side up (upright).
Do convex mirrors produce virtual images?
For convex mirror, Object distance u is negative and the focal length f is positive. Therefore, the image distance is always positive incase of a convesx mirror. Hence, the convex mirror always formed a virtual image.
What are the characteristics of a concave mirror?
Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.
What is an example of a convex mirror?
The most commonly seen example of a convex mirror is the side view mirror on a car. Convex mirrors are seen in dome mirrors found in offices and stores for security and anti-theft purposes.
What is a concave mirror?
Sometimes referred to as a converging mirror, the concave mirror is made with a surface that bends inward. Because the center of the curve is directed away from any incident light, it creates a reflection that is typically larger than the actual focal point.
What is the focal point of a concave mirror?
A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point.They are used to focus light.
