Questions and Answers

1.

The virtual image produced by a plane mirror appears to be the same distance away from the mirror as the object itself.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
A plane mirror reflects light rays in a way that they appear to come from behind the mirror. This creates a virtual image that is formed at the same distance behind the mirror as the object is in front of it. This is because the angle of incidence is equal to the angle of reflection, causing the reflected rays to appear to originate from the same distance as the object. Therefore, the statement is true.

A plane mirror produces a top-to-bottom reversal and a left-to-right reversal.
- A.
  
  True
- B.
  
  False

3.

The height of an image as seen in a plane mirror is the same as the actual height of the object.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
When an object is placed in front of a plane mirror, the image formed is virtual and appears to be behind the mirror. The image is a reflection of the object and is of the same size as the object. Since the distance between the mirror and the object is the same as the distance between the mirror and the image, the height of the image is equal to the actual height of the object. Therefore, the statement is true.

Virtual images are formed from divergent rays
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Virtual images are formed by the apparent intersection of diverging rays. These rays do not actually converge to a point but appear to do so when traced back. This is in contrast to real images, which are formed by the actual convergence of rays. In the case of virtual images, the rays appear to diverge from a point behind the mirror or lens, resulting in an image that cannot be projected onto a screen. Therefore, the statement "Virtual images are formed from divergent rays" is true.

What is the size and position of an image formed by a plane mirror?
- A.
  
  Same size, closer to the mirror
- B.
  
  Same size, same distance away from the mirror
- C.
  
  Enlarged, closer to the mirror
- D.
  
  Reduced, farther from the mirror
Correct Answer
B. Same size, same distance away from the mirror

Explanation
When an image is formed by a plane mirror, it is always the same size as the object and is located at the same distance away from the mirror as the object is. This is because a plane mirror reflects light rays in a way that preserves the size and distance relationships between the object and its image. Therefore, the correct answer is that the image formed by a plane mirror is the same size and at the same distance away from the mirror as the object.

If di= -do, then what is the meaning of the negative sign?
- A.
  
  The image is inverted
- B.
  
  the image is smaller
- C.
  
  The image is virtual
- D.
  
  the image is larger
Correct Answer
C. The image is virtual

Explanation
the minus means the image is behind the mirror- so virtual

A man stand two meters away from a plane mirror. How far is it from the man to his image?
- A.
  
  2.0 m
- B.
  
  3.0 m
- C.
  
  4.0 m
- D.
  
  5.0 m
Correct Answer
C. 4.0 m

Explanation
When a person stands in front of a plane mirror, the image appears to be the same distance behind the mirror as the person is in front of it. Therefore, the distance from the man to his image is also 2 meters.

When the reflection of an object is seen in a plane mirror, the distance from the mirror to the image depends on:
- A.
  
  The wavelength of light used for viewing.
- B.
  
  . the distance from the object to the mirror.
- C.
  
  The distance of both the observer and the object to the mirror.
- D.
  
  the size of the object.
Correct Answer
B. . the distance from the object to the mirror.

Explanation
The distance from the mirror to the image depends on the distance from the object to the mirror. This is because the image formed by a plane mirror is virtual, meaning it is formed by the apparent intersection of the reflected rays. The rays of light from the object bounce off the mirror and appear to come from behind the mirror, creating the image. The distance between the object and the mirror determines the angle at which the rays reflect and thus affects the position of the image.
