Question

The image of a clock in a plane mirror shows a wrong time as 08:45. Assuming the clock did not have number markings on it, the correct time would be:

• A. 2:45
• B. 3:15
• C. 3:45
• D. 4:15

Answer 1

The correct option is B 3:15

Remember, an extended object like a clock will form a laterally inverted image in a plane mirror. That is, left and right will be interchanged. So, as the time the image clock shows is 8:45, it will look like:

Hence the real clock would look like:

Hence, the correct time is 3:15.
