Question

DATA SHEE PARTI: Reflection, Mirrors, and Focal Length Measurements Section A: Reflection from a Plane Mirror Table A 0. 54 percent error 5.26% trial1 57 trial 2 30 26 13.3% trial 3 72 70 2.78% percent error = x 100% BE ection B1: Reflection from a Concave Mirror Focal Length of the Concave Mirror: f81= 5.50cm Radius of Curvature of the Concave Mirror: R$1= llum ction B2: Reflection from a Convex Mirror Focal Length of the Convex Mirror: fb2= 5.50cm Radius of Curvature of the Convex Mirror: RB2= -llom percent difference = RB1-RB2 average *100% = 200 x 100 11

All I need is the index of refraction from the info above if thats possible! Thanks!
