Questions Related to terms related with spherical mirrors

A real image :

physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

  1. cannot be captured on a screen

  2. can be captured on a screen

  3. can be captured only on a celluloid screen

  4. none of the above

Show answer
Correct Option: B
Explanation:

Real image can be captured on a screen.

If image is formed behind the mirror, it is:

physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

  1. real and inverted

  2. virtual and erect

  3. virtual and inverted

  4. real and erect

Show answer
Correct Option: B
Explanation:

If the reflected rays are extended behind the mirror, then their intersection gives the location of the image behind the mirror. For a convex mirror, the image is diverging, virtual and upright and is formed behind the mirror. 
Hence, if image is formed behind the mirror, it is virtual and erect.

The image of our face in a plane mirror is :

physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

  1. real

  2. magnified

  3. diminished

  4. virtual

Show answer
Correct Option: D
Explanation:

For a plane mirror the image formed is behind the mirror, so by definition its virtual

A real image is formed where two or more :

physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

  1. reflected rays meet

  2. refracted rays meet

  3. reflected rays appear to meet

  4. refracted rays appear to meet

Show answer
Correct Option: A,B
Explanation:

For a real image to be formed, two light rays have to actually intersect by definition.

Is it possible to photograph a virtual image?

physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

  1. Yes

  2. No

  3. Sometimes

  4. Yes, provided that object is virtual

Show answer
Correct Option: A
Explanation:

Virtual objects can be captured or photographed as the rays appears to originate from it.

The image of an object which cannot be obtained on a screen is called-

physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

  1. Enlarged image

  2. Real image

  3. Virtual image

  4. Inverted image

Show answer
Correct Option: C
Explanation:
$ \bf{Real\ Images}$ are images which can be obtained on the screen. They are formed when light rays after getting reflected from a mirror actually meet at a point. 
A real image is inverted with respect to the object.

$ \bf{Virtual\ Images} $ are images which can be only be seen in a mirror bur cannot be obtained on the screen. They are formed when light rays after getting reflected from a mirror appear to meet at a point. A virtual image is erect with respect to the object.

Thus, real and inverted image can be obtained on the screen. Also, depending upon the optical instrument used, the real and inverted image can be enlarged or diminished implying that real, inverted and enlarged images are obtainable on screen.  

Hence, the correct answer is OPTION C.

The image formed by a plane mirror is -

physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

  1. virtual

  2. inverted

  3. diminished

  4. magnified

Show answer
Correct Option: A
Explanation:

A plane mirror always forms an image which is virtual in nature (meaning that light rays meet behind the mirror or that light rays do not actually come from the image), erect and of the same shape and size as that of the object it is reflecting.
Hence, the correct answer is OPTION A. 

An image which can be only seen by the eye but cannot be taken on a screen is called a ________ .

physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

  1. virtual image

  2. real image

  3. artificial image

  4. shadow

Show answer
Correct Option: A
Explanation:

Virtual images cannot be taken on screen as they are not formed by actual intersection of light rays.

Pick the odd one out of these :

Real image, virtual image, inverted image, diminished image

physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

  1. Virtual image

  2. real image

  3. inverted image

  4. diminished image

Show answer
Correct Option: D
Explanation:
Diminished image is odd one out as it is related to size.

Name : The image which cannot be obtained on the screen 

physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

  1. Virtual image

  2. Erect Image

  3. Real Image 

  4. Inverted Image 

Show answer
Correct Option: A,B
Explanation:

since we know that for an image to be obtained on screen rays should intersect on the screen but virtual image is formed by no actual meeting of rays hence it is not possible to be obtained on screen. we can observe from all the virtual images formed, they are always errect.
