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 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. 

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

When a  beam of light from an object appears to meet at a point after reflection from a mirror then the image formed is known as:

  1. Real image

  2. Virtual image

  3. Incident image

  4. All
Reveal answer Fill a bubble to check yourself
B 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. 

$ \bf{Virtual\ Images} $ are images which can only be seen in a mirror but cannot be obtained on the screen. They are formed when light rays after getting reflected from a mirror appear to meet at a point. 

Hence, the correct answer is OPTION B.

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

When a beam of light from an object meets actually at a point after reflection from a mirror then the image formed is known as

  1. Real and virtual image both

  2. Real image

  3. Virtual image

  4. No image
Reveal answer Fill a bubble to check yourself
B 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. 

$ \bf{Virtual\ Images} $ are images which can only be seen in a mirror but cannot be obtained on the screen. They are formed when light rays after getting reflected from a mirror appear to meet at a point. 

Hence, the correct answer is OPTION B.
Multiple choice physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

Choose the correct statement about real and virtual images:

  1. Real images can be obtained on a screen, whereas virtual images cannot be obtained on the screen.

  2. Virtual images can be obtained on a screen, while real images cannot be obtained on a screen.

  3. Virtual images are formed only in refraction not in reflection, while real images can be formed in both reflection and refraction.

  4. Virtual images are formed only in reflection, while real images are only formed in refraction.
Reveal answer Fill a bubble to check yourself
A 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 only be seen in a mirror but 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. 

Hence, the correct answer is OPTION A. 
Multiple choice physics curved mirrors real and virtual image real and virtual images terms related with spherical mirrors

A movie projector forms real images. Why is it not inverted?

  1. Real images are erect in nature.

  2. Final image is formed using virtual image.

  3. Multiple mirrors are used

  4. Films are inverted
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A movie projector uses two mirrors. First is used to concentrate light source and second is used to focus the images on the screen. Since images are inverted twice, final images are erect. 

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

A virtual image larger than the object can be produced by a

  1. Concave lens

  2. Concave mirror

  3. Convex mirror

  4. Plane mirror
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A $ \bf{concave\ lens} $ always produces virtual, erect and diminished images and the decrease in the size of the image depends on the position of the object.

$ \bf{Concave\ mirrors} $ produce real and virtual, erect and inverted, diminished same sized and magnified image depending upon the position of the object on the principal axis. But the concave mirror forms a virtual and enlarged image when the object is placed between the Focus and the pole of the mirror.

$ \bf{Convex\ mirrors} $ always produce a virtual, erect and diminished image and the decrease in size of image depends on the position of the object in front of the mirror.


$ \bf{Plane\ Mirrors} $ always produce a virtual and erect image having the same size as that of the object irrespective of the position of object.

Hence, the correct answer is OPTION B.
