Q6

#### Consider the following statements and choose the incorrect one:

[A]. A mirror changes the direction of light that falls on it.
[B]. This change in direction of light by a mirror is called reflection of light.

Q7

#### 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.
Q8

#### 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.
Q9

#### Badal appeared in class test but he confused to know the correct statement. Would you help him to know that?

[A]. Concave mirror and convex mirror are called spherical mirrors
[B]. When the parallel rays of light are getting closer together after reflection, we say that the rays of light are converging.
[C]. When the parallel rays of light are spread out after reflection, we say that the rays of light are diverging.
[D]. All the above
Q10

#### 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.
Q11

#### Recently, in a science class test, you are asked a question where you have to say whether the statements are correct or not?

[D]. None of the above
Q13

#### Which of the following statement is or are correct?
