Q.

Difference between real and virtual image

Q. When does a plane mirror form a real image

Q.

What are the important differences between looking at a photograph of your face and looking at yourself in a plane mirror ?

Q.

Why are real images always inverted?

Q.

A full-length image of a distant tall building can definitely be seen by using:

1. A concave mirror

2. A convex mirror

3. A plane mirror

4. Both concave as well as plane mirror

Q. The focal length of a concave mirror is 10 cm. The position of the object that is useful for
getting an enlarged image, which can be caught on a screen is

Q.

The magnification produced by a spherical mirror is -2. List four information you obtain from this statement about the mirror/image.

Q. Why do we see our image on the concave mirror when it it actually a real image and formed in front of the mirror

Q.

Can we see inverted images in the plane mirror?

Q.

Why in convex mirror only 2 cases are possible

Q. Which of the following is true regarding the image formed by a concave mirror?

1. A real image is always diminished.
2. A virtual image is always magnified.
3. A virtual image is of the same size as the object.
4. A real image is never diminished.

Q.

Which of the following can produce a virtual image?

1. Plane mirror

2. Concave mirror

3. Convex lens

4. All of the above can produce a virtual image

Q.

Identify the condition, which will form a real, inverted and enlarged image.

1. concave lens, object placed between focus F & pole O.

2. convex lens, object placed beyond 2F1.

3. convex lens, object placed between F1 and 2F1.

4. concave mirror, object placed between C & F.

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

1. Virtual image can be obtained on a screen while real images cannot be obtained on a screen
2. Real image are the image that can be obtained on a screen whereas virtual image cannot be obtained on the 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

Q.

Are real images always inverted?

Q.

What is the difference between a real image and a virtual image ? Give one example of each type of image.

Q. Is it possible to form an real image using convex mirror
(or) only virtual images will be formed buy convex mirror
If real images are formed by convex mirror then please send a diagram showing the formation of real image through convex mirror and show the diagram along with (F, C, v, u, )

Q. Real and virtual image
where does real image form plane , concave , convex mirror and how?

Q.

The nature of the image formed by the convex mirror is always

1. Real and inverted

2. Virtual and inverted

3. Real and erect

4. Virtual and erect

Q. Write three differences between a real image and a virtual image.

Q.

Which among the following is not true for a plane mirror?

1. Image is always formed at infinity

2. Image formed by a plane mirror is always virtual

3. Image formed is always erect.

4. Lateral inversion always takes place in a plane mirror

Q. Is it possible to photograph a virtual image?

1. Yes
2. No
3. Sometimes
4. Yes, provided that object is virtual

Q.

You are given three mirrors of different types. How will you identify each one of them?

Q. Question 20
Identify the device used as a spherical mirror or lens in following cases, when the image formed is virtual and erect in each case.

(a) Object is placed between device and its focus, image formed is enlarged and behind it.

(b) Object is placed between the focus and device, image formed is enlarged and on the same side as that of the object.

(c) Object is placed between infinity and device, image formed is diminished and between focus and optical centre on the same side as that of the object.

(d) Object is placed between infinity and device, image formed is diminished and between pole and focus, behind it.

Q.

Which of the following mirror will always form virtual and diminished image irrespective of object location?

1. parabolic concave mirror

2. plane mirror

3. convex mirror

4. concave

Q.

The bending of light on passing from one medium into another is called _____________.

Q.

What are the characteristics of an image which is formed by a plane mirror?

Q.

Which of the following mirror forms an image which is virtual and smaller in size

1. convex

2. concave

3. plane

4. all of these

Q.

Draw ray diagram and state the properties of the image formed for an object kept, ​

1. between the focus and the centre of curvature of a concave mirror. ​

2. In front of a convex mirror.​

Q. A real image is always .......(inverted/ magnified).
