At what object distance would a convex lens not form an image Brainly?
Answer. Answer: The object should be at a distance less than the focal length from the convex (converging) lens in order to get a virtual image.
At what position should an object?
Answer. Answer: For real, inverted and reduced image, the object must be placed beyond the centre of curvature.
Where should an object be placed in front of a convex lens so as to form an upright and enlarged image?
To form an inverted and enlarged image by a convex lens, the object should be placed between F and 2F infront of the lens.
What is the front of a convex lens?
Image formation in convex lenses A) When an object is placed in front of the front focal point (F) of a lens, an inverted real image is formed at a specific distance from the back focal point F’. B)
Can a convex lens always forms an image?
Answer: A convex lens can form real and inverted image. When the object is placed very close to the lens, the image formed is virtual, erect and magnified. A concave lens always forms erect, virtual and smaller image than the object.
What lens is thinner in the center than at the edges?
Concave
Which lens is thicker at the edges?
A concave lens is thicker at the edges than it is at the center, and a convex lens is thicker in the middle than it is at its edges.
What kind of lens has thin edges?
Comparison Chart
| Basis for Comparison | Concave Lens |
|---|---|
| As known | Diverging lens |
| Shape of the optical surface | In concave lens, the centre of the glass piece is thin while the edges are thick. |
| Polarity of focal length | Negative, thus sometimes referred as negative lens. |
| Behaviour | It diverges the light rays. |
What kind of lens makes things look smaller?
concave
Is it possible to 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.
What happens to the image size and its location as the object comes nearer the concave lens?
The object changes when it comes nearer the concave lens. The forming image is always at the place between the f and 2f. That is why it is being reduced. While the convex lens creates the opposite one.
