Question

Choose the correct statement about real and virtual images:
A. Real images can be obtained on a screen, whereas virtual images cannot be obtained on the screen.
B. Virtual images can be obtained on a screen, while real images cannot be obtained on a screen.
C. Virtual images are formed only in refraction not in a reflection, while real images can be formed in both reflection and refraction.
D. Virtual images are formed only in reflection, while real images are only formed in refraction.

Answer 1

Hint: Before attempting this question one should have prior knowledge about the real and virtual image and position at real and virtual images are formed, use this information to approach towards the solution to the question.

To find the correct option let’s first discuss the image which can be defined as the projection of collection of points emitted by the object it is of two types real image and virtual image.
Real Images can be defined as the projection of images that is viewed on the display, when a light ray projected from an object after getting reflected by a mirror it finally meets at a point where the real image of object is projected and the image of the object in this case is observed inverted with respect to object.
Such images which can only be visible through a mirror and those images that cannot be viewed on the display like real images and such types of images formed when a light rays projected from object and appear to intersect at a point once they get reflected by the mirror in this type of image the image of object is erect comparison to the object.
Therefore we can say that virtual images cannot be obtained on the screen whereas the real images can be obtained on a screen
Hence option A is the correct option.

Note: In the above solution we used the term “Reflection” which can be explained as the difference in the direction of light projected from source when the light strikes the different medium the direction of light changes in such a way that the light is pushed back to the medium from where it is projected. Some examples of reflection are when you project light on a mirror you observe that the light is bounced back by the mirror in a different direction.
