Ncert- science – class 7- Chapter 11 – Light 2 Welcome to your Ncert- science – class 7- Chapter 11 – Light 2 1. When a convergent beam of light is incident on a plane mirror, the image formed is Upright and virtual Upright and real Inverted and virtual Inverted and real None 2. ...... images cannot be caught on a screen. Real Erect Virtual Inverted None 3. We can see a non-luminous object when light : completely passes through the object emitted by the object falls on the eye is reflected from the object towards our eye gets completely absorbed by the object None 4. Which of the following can produce a virtual image for any position of the object? All of the above Concave mirror Plane mirror Convex lens None 5. The mirror used in search lights is: Concave Plane Convex None of these None 6. The image formed by a plane mirror is always ______ inverted. None of these Laterally Virtually Really None 7. A plane mirror:(i) can form real image of a real object(ii) neither converges not diverges the rays(iii) cannot form real image of a real objectChoose the correct option or options. (i) is correct None of the above (ii) and (iii) are correct (i) and (ii) are correct None 8. When a convergent beam of light is incident on a plane mirror, the image formed is Inverted and virtual Upright and virtual Inverted and real Upright and real None 9. Mirror used as rear view mirror is Convex Plane Either convex or concave Concave None 10. A diminished virtual image can be formed only in:- A concave mirror Concave-parabolic mirror. plane mirror A convex mirror None 11. A ray of light is incident on a plane mirror at an angle of incidence 30 degree to the normal. The ray after reflection is deviated with an angle of: 40 degree 50 degree 30 degree 120 degree None 12. The concave mirrors are used in: Magic-lanterns Cinema projectors Reflecting telescope All of these None 13. Which mirror should be used to obtain a parallel beam of light from a small lamp? None of the above Convex mirror Plane mirror Concave mirror None 14. Select the correct alternative:The property due to which a light ray striking a surface and returned back into the same medium is called reflection refraction regression reflex action None 15. A virtual image is one which: Cannot be taken on a screen Sometimes can be and sometimes cannot be taken on a screenpp Is formed only by a concave mirror Can be taken on a screen None Time's up Please Share This Share this content Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Leave a Reply Cancel replyCommentEnter your name or username to commentEnter your email address to commentEnter your website URL (optional) Save my name, email, and website in this browser for the next time I comment.
