Q. A person who used a concave lens saw an image. without specs, he couldn't see an image clearly which was far away. If we place a mirror closer to him he could see a mirror (object) but he can not see an image(at a long distance) which was reflected by a mirror.Why he could not see an image clearly even though the mirror was closer to him. ?

Q. Image-1 and 2 are formed when a pinhole camera and a magnifying glass is placed in the place of box-X. Choose the correct statement(s):​

1. Image-2 is brighter​
2. Image-1 is brighter​
3. Image-2 is clearer​
4. Image-1 is clearer​

Q.

The reason behind the formation of shadow and image are

1. None of these

2. They are different

3. They are congruent in shape

4. The are similar in shape

Q.

The image formed in a pinhole camera is inverted. Why?

1. Because of reflecting property of the light

2. Because of high speed of light

3. None of these

4. Because of the rectilinear propagation of light.

Q. Real images formed by mirrors are always

1. inverted
2. magnified
3. squiggly
4. erect

Q. Real images formed by mirrors are always

1. inverted
2. magnified
3. erect
4. squiggly

Q. What is an image?

Q. Why does the pinhole camera produce an inverted image ?

1. The light passing through a convex lens produces an inverted image
2. The light passing through a concave lens produces an inverted image
3. The light travelling in a straight line passes through aperture to produce an inverted image
4. Pinhole camera produces an upright image
