  4. Telescope
Reveal answer Fill a bubble to check yourself
C,D Correct answer
Explanation
For compound microscope -The final image is virtual, inverted and magnified.
The final image formed by an astronomical telescope is always virtual, inverted.
Camera and projector always form erect image.
Multiple choice physics observing space: telescopes space research and satellites space travel space exploration and forms of light

The final image formed by an astronomical telescope is

  1. real and erect

  2. virtual and erect

  3. real and inverted

  4. virtual and inverted
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An astronomical telescope is an optical instrument which is used to see the magnified image of distant heavenly bodies. The final image formed by an astronomical telescope is always virtual, inverted and magnified.

Multiple choice physics observing space: telescopes space research and satellites space travel space exploration and forms of light

In an astronomical telescope, the intermediate image is

  1. virtual, erect and magnified

  2. real, erect and magnified

  3. real, inverted and reduced

  4. virual, inverted and reduced
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Astronomical telescope in which the image is inverted$,$ is n of the two principle types of the telescopes$.$ Its primary function is to enlarge the retinal image of a distant object$.$

hence,
option $(C)$ is correct answer.

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.

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

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.
