(D) opt as we can definitely capture image of virtual image when we take photo of the mirror and the virtual image is defined correctly

Ans 2:

both r not correct

Ans 3:

arnav raj sharma from gulibulium school, new york
Class : Class 8
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

Ans 4:

shashwat pandey from Doon International School Dalanwala, Dehradun

Ans 5:

Adhrit from CHSV, Chennai

Virtual images is NOT defined correctly, because in a plane mirror parallel rays of light stay parallel. There is no divergence, but it's still a virtual image formed. So the correct answer should be both statements are false, which isn't an option for some reason
