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.
[C]. After reflection also, the light continues to travel in a straight-line path.
[D]. None of the above.
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?

[A]. A lens is a piece of transparent glass bound by two spherical surfaces.
[B]. Mirrors are not transparent, so light rays cannot pass through mirror.
