Real Image

Q. What is the difference between virtual and real image?

Q.

4. a cylindrical wavefront

Q.

Q.

As the object moves towards a concave mirror from infinity, the image will

1. keep getting enlarged

2. keep getting diminished

3. keep getting blurred

4. move towards the mirror

Q.

Can the virtual image be obtained on the screen?

Q.

Difference between real image and virtual image

Q.

Paragraph : When the rays of light after being incident on a mirror, get reflected, two situations are possible. The rays may either intersect actually or they may diverge; in which case if extrapolated they appear to intersect. A real image is formed in the former case and a real image in the later.

Q If converging incident rays fall on a convex mirror:

1. A real image will be formed

2. A virtual image will be formed

3. Any type of image may form depending upon from where the rays are coming

4. Can not comment

Q.

How does virtual image forms?

Q.

A convex mirror has the largest field of view among all the mirrors. This property is used in

1. make-up mirrors

2. telescopes

3. rear-view mirrors

4. all of the above

Q.

A real image is formed by a mirror when:

1. Reflected Rays actually intersect

2. Reflected Rays appear to intersect

3. When the objects is real

4. Can’t comment

Q.

A convex mirror will form a real image for a virtual object

1. True

2. False

3. A convex mirror cannot form a real image

Q.

1. Less than 5 cm

2. More than 5cm

3. Equal to 5 cm

4. Can’t calculate with the given data

Q.

A real image is formed by a mirror when:

1. Reflected Rays actually intersect

2. Reflected Rays appear to intersect

3. When the objects is real

4. Can’t comment

Q.

An object is kept at a distance of 10 cm from a concave mirror of focal length 5 cm, the magnitude of the image is

1. Less than 10 cm

2. More than 10 cm

3. Equal to 10 cm

4. Can’t calculate with the given data

Q. Can a plane mirror form a real image?

Q.

What is the nature of the image formed by a concave mirror if the magnification is $4$?

Q. Image tracing in a plane mirror means

1. Checking out the apparent or real point of convergence of light rays before reflection
2. Checking out the apparent or real point of convergence of light rays after reflection
3. Both of them
4. None of them

Q. Statement I : Rays incident on a convex mirror from a point source of light, after reflection diverge.
Statement II : A convex mirror can never form a real image for a point source of light.

1. Both the statements are correct and Statement II infers from Statement I
2. Both the statements are correct but Statement II doesn’t infers from Statement I
3. Statement I is correct but Statement II is incorrect
4. Statement I is incorrect and Statement II is correct

Q.

If we cover half of a concave mirror, the image size will

1. Reduce to half

2. Double

3. Will remain same

4. Can’t comment with the given data

Q.

Find the magnitude of image for an object at a distance of 10 cm from a concave mirror of focal length 5 cm

2. More than 10 cm

3. Equal to 10 cm

4. Can’t calculate with the given data

Q.

will erect image always be virtual ? explain i m having confusion. will inverted image always be real:?

Q. Assertion :Real images form on the side of a refracting surface that is opposite to the object and virtual images form on the same side as the object . Reason: Virtual images cannot be taken on screen.

1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
3. Assertion is correct but Reason is incorrect
4. Both Assertion and Reason are incorrect
