question number 4

 

[JOEJOE]

this is complicatd look.. the pins image is reflected so the same distance from the mirror as p1 and p2 put p3 and p4.. SAME distance..

to measure the angle use a protractor find the angle of incidence then subtract it from 90 degress ALWAYS!!!!!!!!!!!!

then for angle of reflection its same as incidence measure and subtract from 90

sec doing the rest

 

[JOEJOE]

pins should be more than 5 cm from each other to be clear... also lines are thin to be able to measure angles properly since thickness affects readings
