Mr. Ang, can you help clarify question 2,3,6,7,8,and 10?
Also, may I ask what's the difference between real and virtual? Thank you
-Yue Min and Rei Yin

I have discussed the questions in class, but let me know if any further query.
A real image is one that can be formed on a screen (or any surface, hence seen by the eye) like what you did in experiment PR1.
A virtual image is one that cannot be formed on a screen (but can only be seen with the eye), e.g. image seen using a magnifying glass, image seen in a mirror.
