Ans 6:

arnav raj sharma from gulibulium school, new york

the correct answer is (b) as a virtual image cannot be captured on a screen which means it cant be photographed so statement 1 is correct and a virtual image is formed by a convex mirror and It has diverging rays so a virtual image can also be defined as an image formed by diverging rays so statement two is correct but the reason for first statement is that a virtual image cannot be captured on a screen so (b) is the correct answer
