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
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
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.
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
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
2 ) Virtual and enlarge pic formed ☺
plz plz mark it as brainliest
sure bro! shall follow asap!
