Only a concave mirror is capable of producing a real image and this only occurs if the object is located a distance greater than a focal length from the mirror’s surface. 10.
Which type of mirror can form a real image class 7?
A concave mirror can form a real image. Concept insight: Concave mirror can form real as well as virtual image depending on the position of the object, while a convex mirror always forms virtual image for all positions of the object. A concave lens always forms a virtual image of an object.
Can a concave mirror form a real image?
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. ... The objective lens gathers the light from the object and projects a real image within the structure of the optical instrument.
Can a convex mirror form a real image of an object?
convex mirrors can produce real images as well . If the object is virtual, i.e., if the light rays converging at a point behind a plane mirror (or a convex mirror) are reflected to a point on a screen placed in front of the mirror, then a real image will be formed.
Which is used to form a real image?
Only a concave mirror can form a real image. Plane mirror and convex mirror always form a virtual image of an object.
Which can form a real image?
Solution: Concave mirrors can form real images. Convex and plane mirrors always form virtual images.
Are real images always inverted?
Real image is found when the rays of light converge at a point after reflection on a mirror or after refraction through a lens. ... If we placed an object above the x-axis then by geometry the rays will converge below the axis. Therefore, the image formed will be an inverted image. Hence, a real image is always inverted .
What image does concave mirror form?
Concave mirrors form both real and virtual images . When the concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.
What are the 6 cases of a concave mirror?
- Object at infinity.
- Object between infinity and centre of curvature (C)
- Object at centre of curvature (C)
- Object between centre of curvature (C) and Principal focus (F)
- Object at Principal Focus (F)
Which mirror is used in street light?
Hence, comparing all the given options, it can be concluded option B is correct; a street light bulb uses the convex mirror as reflectors. Note: Reflectors light bulbs are generally used in the heavy light application, in floodlights and in spotlights. Reflectors are used because they can spread light in a large area.
What is the difference between a real image and virtual image?
An image formed when the light rays converge at a particular point after refraction and reflection is known as a real image. An image formed when rays appear to meet a particular point after the reflection from the mirror is known as a virtual image.
How do you tell if a mirror is concave or convex?
Only a concave mirror is capable of creating a real image and this only occurs if the object is situated at a greater distance than the focal length of the mirror’s surface. The image formed in a convex mirror is always virtual and erect, whatever be the position of the object.
What is image formed by plane mirror?
Images formed by plane mirrors are virtual, upright , left-right reversed, the same distance from the mirror as the object’s distance, and the same size as the object.
Which of the following Cannot be used to form a real image?
Concave mirror . Convex mirror. Plane mirror.
Can you give an enlarged and erect image of an object?
Solution : Concave mirror forms an erect, virtual and enlarged image when the object is between focus and pole of mirror.
Can we see real image?
A real image can be viewed on a screen , a virtual image can not. Rays from both types can enter your eye, be refracted by your eye’s lens and form a real image on your retina as @CarlWitthoft points out. So it is not the case that a real image must be viewed on a screen. It can be viewed on a screen.
