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.

What is the basic difference between a real image and a virtual image ?

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

  1. Real image are the image that can be obtained on a screen whereas virtual image cannot be obtained on the screen

  2. Virtual image 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 image can be formed in both

  4. Virtual images are formed only in reflection while real image are also only found in refraction

Show answer
Correct Option: A
Explanation:

Virtual image are the images that can be obtained on screen while real images can't be obtained on a screen. This is basic difference between real and virtual image.

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:

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

  1. Real image

  2. Virtual image

  3. Incident image

  4. All

Show answer
Correct Option: B
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.

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

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

  1. Real and virtual image both

  2. Real image

  3. Virtual image

  4. No image

Show answer
Correct Option: B
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.

Choose the correct statement about real and virtual images:

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

  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.

Show answer
Correct Option: A
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. 

Rear view mirrors in vehicles forms:

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

  1. Real Image

  2. Virtual Image

  3. Both A and B

  4. Neither A nor B

Show answer
Correct Option: B
Explanation:

In rear view mirrors, convex mirrors are used. They form virtual and erect images.

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

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

  1. Real images are erect in nature.

  2. Final image is formed using virtual image.

  3. Multiple mirrors are used

  4. Films are inverted

Show answer
Correct Option: C
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. 

Real image can be obtained on a screen.

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

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

The given statement is true that we can  obtain the real image on the screen but not the virtual image.

Virtual image cannot be caught on a screen.

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

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

Only real image can be obtained on screen but not the virtual image. So the given statement is true.

Virtual image can be caught on a screen.

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

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

For any image to be formed on a screen we need to have actual rays intersecting on the screen. Hence only real image can be taken on a screen.
