What happens to the image if half of a mirror is painted black?

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 will happen to the image formed by a concave mirror if its half portion is painted black?

(i) Image formed will be inverted diminished between C and F. ii) When the lower half of the mirror’s reflecting surface is painted black, the position of the image and its intensity will get reduced.

What will be the effect on the image of an object produced by a concave mirror is covered by a non reflecting material up to half of its size?

(b) If lower half of the concave mirror is covered with an opaque material, the size of the image will not vary. But, since the reflecting surface has been reduced, the intensity of the image will be less. That is, brightness of the image will decrease.

What is the image on the cover of mirrors?

When you place an object in front of a mirror, you see the same object in the mirror. This image that appears to be behind the mirror is called the image. The object is the source of the incident rays, and the image is formed by the reflected rays. An image formed by reflection may be real or virtual.

What happens when a mirror is half covered?

Only the brightness of the image of the object will be affected. But the intensity of the image of the object will be reduced. As the reflected rays will be less.

What if half portion of lens or mirror is covered with black paper?

The image produced will be complete. But the image observed now will be fainter. Even when half of the mirror is covered with black paper, it would still produce a complete image but the image produced would be fainter (of lesser intensity) than the image produced when half mirror was not covered.

What is the shape of upper half of the mirror?

(a) the top part of the mirror is convex, as it forms virtual, erect and small-sized image.

Is lower half of concave mirror is black and then?

Because of doing so, aperture decreases and so, less no. of light rays produce the image and so intensity of image decreases.

What kind of image is formed by a concave mirror?

Both real and virtual images are formed by the concave mirror. When the object is placed very close to the mirror, a virtual and magnified image is formed.

When someone dies do you cover the mirror?

You should cover the mirror in a house where there’s been a death because the soul of the dead person wanders around for three days, and it should not see itself in the mirror—if this happens the mirrors will tarnish and never be clean again, or in days to come the mirror will turn and make a picture of the dead.

Why do they cover mirrors when someone dies?

The Irish wake is a well-known funeral tradition where the family of the deceased covers all mirrors in the home. To hide the physical body from the soul, the family turns mirrors to face the wall. They cover mirrors with black material to ease the deceased’s journey into the afterlife.

What happens when a mirror is covered with black paper?

Explanation: If the plane mirror is covered with a black paper then the complete image of the object will be formed. It does not matter how much portion of the mirror is covered. But the intensity of the image of the object will be reduced.

What will happen if the lower half of a mirror is blocked?

, I see the world through lenses. Blocking lower half will make the mirror look like a semi circle. It won’t affect the nature of image. The image will be less brighter than that formed by a full mirror. It is because image will be formed by the rays reflected from the upper half only.

Will a half of a convex mirror produce a complete image?

One half of a convex mirror covered with a black paper.Will it produce complete image of object? image will still be formed because light rays will go from the upper half of the lens which is sufficient of the image formation but the intensity of the image will be low.

What happens if half of the lens is covered with black paper?

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. So brightness also decreases. Hope it will help you. Due to covering the lower half light rays from lower part is not there.So it makes the image less bright.

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.
