it's important to know the type of questions that appear in exams :)

object and orientation in the mirror

• try turing the page such that the mirror is upright (easier to visualize)

• use the 5 properties (L O V E U)

what is the correct angle of incidence OR relfection

• all

• 
  

people in front of mirrors (aka vain pot question)

• try drawing where the image will be

• always identify the image and object distance :)

Poll
