Can you have a virtual image with two lenses?

Only a converging lens can be used to produce a real image; and this only occurs if the object is located at a position of more than one focal length from the lens. 2. A converging lens will only produce a virtual image if the object is located in front of the focal point.

What is a virtual object in optics?

A virtual object is one from which light rays appear to emanate but physically do not. • A virtual image is one in which light rays do not physically intersect at the image point but appear to diverge from that point.

What are the 2 types of lens explain?

The two main types of lenses are:

• Convex Lens (Converging)
• Concave Lens (Diverging)

How do you tell if an image is virtual or real?

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).

What is the difference between real 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.

Can a virtual image be a real object?

Yes it is possible. The best example would be :- 1) Suppose a condition in which you are looking at you image in a plane mirror. The mirror forms a virtual image of your, now when you are looking at the mirror on your image then a a real image of the mirror image is formed on your retina.

How do you tell if an object is virtual or real?

Can diverging lens create real image?

Plane mirrors, convex mirrors, and diverging lenses can never produce a real image. A concave mirror and a converging lens will only produce a real image if the object is located beyond the focal point (i.e., more than one focal length away). The image of an object is found to be upright and reduced in size.

Where is convex lens used?

Convex lenses are used in microscopes, magnifying glasses and eyeglasses. They are also used in the cameras to create real images of objects present at a distance. The nature of the images depends on the way these lenses are used.

How can rays come from this virtual object towards the lens?

How can rays come from this virtual object towards the lens, from the right , and again the image is formed at the right hand side. This is possible only in concave lenses and in convex lenses when the object is between P and F. But neither of the cases apply here.

Which is the virtual object in Interface 2?

The virtual object for interface 2 is where the light seems to be coming from, means in exactly opposite direction of l1 along the ray of light. Because, it is a “would have been image”, and virtual object is directly opposite, the virtual object and final image are not on the same side.

Why are virtual objects not on the same side?

Because, it is a “would have been image”, and virtual object is directly opposite, the virtual object and final image are not on the same side. A virtual object is a convenient fiction that you’d introduce when you need a source of converging light that would allow you to analyze part of your system in isolation.

What are the distances of the two lenses?

Two lens system – Image distance and magnification. Home Problems and Answers Optics Two lens system – Image distance and magnification. Two converging lenses, with the focal length f1 = 10 cm and f2 = 15 cm are placed 40 cm apart, as shown on the figure. An object is placed 60 cm in front of the first lens as show in second figure.
