Q6
Priya is writing some statements, choose the incorrect statement and help her:
[A]. The smooth surface pf still water can also act as a mirror.
[B]. A shining silvered mirror reflects back almost all the light which falls on it.
[C]. We can see the objects around us because they reflect light received from a non-luminous object.
[D]. Most of the objects around us have unpolished and dull surfaces due to which they reflect only a small amount of light falling on them.
Q7
Bikash is doing his homework which is given by his teacher. Would you help him to choose the incorrect sentences?
[A]. What we see in the mirror is actually a reflection of our face and it is called the image of our face.
[B]. We can see the image of our face in the mirror because the smooth and shiny surface of mirror produces regular reflection of light.
[C]. We cannot see the image of our face in the sheet of paper because the rough and dull surface of paper produces irregular reflection of light.
[D]. The image which can be obtained on a screen is called virtual image which we can see in cinema screen.
Q8
Payel is completed her science chapter where she wrote some statements. She wants to know whether the statements are correct or not? Payel wants to take help from you:
[A]. Our image in a plane mirror is an example of virtual image.
[B]. The image which cannot be obtained on a screen is called a virtual image.
[C]. It is not possible to obtain a virtual image on the screen because light rays actually do not pass through it.
[D]. None of the above.
Q9
Puja is writing some statements but she confused to know whether the statements are correct or not? If you know the answer to this question, then tell her:
[A]. The nature and size of the image formed by a concave mirror depends on the distance of the object from the concave mirror.
[B]. The focus of a concave mirror is a point in front of the mirror at which parallel rays of light converge after reflection.
[C]. The focus of a convex mirror is a point behind the mirror from which the parallel rays of light falling on convex mirror appear to diverge after reflection.
[D]. None of the above.
Q10
In the last year board examination, Rahul were asked a question where he had to choose the statement which was/were correct? Will you be able to answer this question?
[A]. Convex mirror are used as rear-view mirrors or side view mirrors in vehicles.
[B]. For very distant objects, a convex lens produces a real and inverted image which is much smaller than the object.
[C]. And when an object is brought very close to a convex lens, then a virtual and erect image is formed which is larger than the object.
[D]. All the above.
Q11
In a quiz competition, you are asked a question where you have to choose the statement which is/ are incorrect?

[D]. Concave lens is used as magnifying glass in microscope, telescope etc.
Q13
Which of the following statement is or are correct?
[A]. A lens is a piece of transparent glass bound by two spherical surfaces.
