A virtual image is one which: Cannot be taken on a screen Can be taken on a screen Is formed only by a concave mirror Sometimes can be and sometimes cannot be taken on a screenpp None 2. 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) and (ii) are correct (ii) and (iii) are correct None of the above (i) is correct None 3. 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 120 degree 30 degree None 4. When a convergent beam of light is incident on a plane mirror, the image formed is Upright and virtual Inverted and virtual Inverted and real Upright and real None 5. Which mirror should be used to obtain a parallel beam of light from a small lamp? None of the above Convex mirror Concave mirror Plane mirror None 6. We can see a non-luminous object when light : gets completely absorbed by the object is reflected from the object towards our eye completely passes through the object emitted by the object falls on the eye None 7.
