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

If image is formed behind the mirror, it is:

  1. real and inverted

  2. virtual and erect

  3. virtual and inverted

  4. real and erect
Reveal answer Fill a bubble to check yourself
B Correct answer
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 an object which cannot be obtained on a screen is called-

  1. Enlarged image

  2. Real image

  3. Virtual image

  4. Inverted image

C Correct answer
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 -

  1. virtual

  2. inverted

  3. diminished

  4. magnified
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

Name : The image which cannot be obtained on the screen 

  1. Virtual image

  2. Erect Image

  3. Real Image 

  4. Inverted Image 
Reveal answer Fill a bubble to check yourself
A,B Correct answer
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.
