A convex lens converges light rays on its focus whereas a concave lens diverges the light rays that seem to come from the focus therefore it is virtual.

Convex mirror show a very large view because they collect a large amount of light in a small space to form an upright and diminished image. That is why in rear view mirrors there is written that the objects in the mirror are closer than they appear

Dear mate..

Because real images are images that can be caught on screen . Convex Lens always produce images that can be caught in a screen except one case , when the object is kept at focus F1 and optical centre O .

Virtual images are images that cannot be caught on a screen . These images are produced by concave lens in all cases. ie ,they are found behind the lens.

Hope its helps u... Please mark it as brainliest.

Virtual means when the image if formed behind the mirror

A convex lens is said to have a real focus and a concave lens a virtual focus

As we know a convex lens is also called converging lens the reason being it converges the light rays, coming from a source, on its focus. Hence the image thus formed will be called a real image because it is formed by converging of actual rays of light.

A concave lens on the other hand is also called a diverging lens since the rays of light coming from a source diverges after passing through concave lens hence it appears to be coming from a point at which we see an image. The image is said to be virtual because it is not formed by actual converging of rays.

Here is your answer.
convex lens is said to have a real focus
because it is convergent lens . it absorb the light rays

concave lens a virtual because it is divergent lens.

hope this will help you

Hey frnd 1)Convex lens bends a parallel beam of light rays to form on to a point at a given distance after refraction of light rays through it on the screen so we say this focus as a real focus, whereas the rays appears to be coming from the focus of the concave lens after refraction of light rays through it, which cannot be obtained on to the screen to form a diminished virtual erect irrespective of the position of the object. So convex lens is said to have a real focus and a concave lens a virtual.

2) If the object is placed between focus and optic centre of the convex lens the enlarged virtual erect image is formed on the same side of the lens as the object. #hope helped

Heya !!

In convex lens the rays converge inside to meet at focus but in a concave lens the rays diverge outside and virtually meet at focus.
