What happens to image if we covered half of convex lens by black paper?

When one half of a convex lens is covered with a black paper,the lens will produce the complete image because the light rays incident on the other part of the lens will converge and form the image.

What happens if you cover half of a convex lens?

Cover half the lens If we cover the top half of the lens, the image just gets dimmer. This tells us that light from all parts of the object goes through all of the lens and then forms the image, so we’re losing about half the light from every part of the object when we block half the lens.

What happens to the image if the lower part of the lens is blackened?

Every part of a lens forms a complete image. If the lower part of the lens is blackened, even then complete image will be formed but its intensity will decrease.

How will the image be affected if the lower half of the convex lens is polished such that no light passes through lower half?

there will be no effect.

What happens if the lower half of a convex lens is painted dark?

As only half of the area of the lens is effective in transmitting the rays, the intensity of the image will be reduced to half of that due to the full transparent lens. Full image of less intensity is formed.

What would happen to the image due to a lens if the bottom half of the lens were covered in paint?

But we should know every part of lens refracts light from full object to its full image and hence if you cover half of it you will only reduce it’s intensity not the part of image.

What happens to the image if lower half of a concave lens is painted black?

(i) Image formed will be between the focus and center of curvature, it would be inverted and smaller in size as apparent from the ray diagram. (ii) If the lower half of the mirror’s reflecting surface is painted black, the position of image will be same but its intensity gets reduced.

When half mirror is covered with black paper?

Complete answer: If half of the mirror is covered with black paper then the image shape will remain unaffected. Just intensity of image will reduce as now, number of reflecting rays will be less as no reflection takes place due to the covered portion.

What happens to the image formed by the convex lens?

Image Formation by Convex Lens In case of a convex lens, if we bring the object close to the lens, the size of the image keeps on increasing. As you bring the object more close to the lens, we get the image all the more enlarged.

What kind of image is formed by convex lens?

virtual image
A convex lens forms a virtual image when the object is kept between the lens and its focus but the image formed is an enlarged one.

Which convex lens half covered with black paper will produce?

A convex lens half covered with black paper will produce a complete image of an object We can verify this by obtaining the image of a tree on the screen by using this half covered convex lens that’s full image of an object is produced by this convex lens because the light ray can still pass through its optical centre

What happens to the intensity of an image formed by half-covered lens?

If half of the lens covered with black paper, then the aperture of the lens decreases and hence the intensity of the image formed by a half covered lens decreases.

Should I cover half of my lens with black paper?

So when you cover half of the lens with black paper, you are not letting the refraction happen from that part, inturn reducing the intensity/brightness of the image. A very simple way you can realise this fact is by looking at yourself in a small and a bigger mirror.

What happens if you cover half of a camera lens?

If you cover a half of lens then it won’t receive light and therefore the light rays contributing in the image formation will be less and therefore intensity (or brightness) of image will be reduced. However the full image of the object will be formed at the same position. This thing you can also observe while looking at your face in the mirror.
