hatch (heh595) – reflection refraction imaging HW – yeazell – (55740)12E:R1<0 andR2<0, but|R1|>|R2|,=⇒f >0,therefore convergent.M:R1>0 andR2>0, but|R1|=|R2|,=⇒f=∞,therefore neither convergentor divergent.Thus, lenses B, K, and E are convergentlenses and Lenses A and C are divergent.Alternate (Elegant) Solution:Converging Lens:The glass is thicker onthe axis than at the edge. B, K, and E satisfythese conditions for a converging lens (f >0).Diverging Lens:The glass is thinner onthe axis than at the edge.A and C satisfythese conditions for a diverging lens (f <0).Neutral Lens:The glass has a constantthickness.Rays of light are parallel to thecentral axis on both sides of the lens.Msatisfy this conditions for a non-focusing lens(f=∞).036 (part 1 of 3) 10.0 pointsA thin lens has a crescent shape, which isdefined by two spherical surfacesAandB.The radius of the surfaceAis|RA|= 3a ,and of surfaceBis|RB|=a .The lens issubmerged in a medium.ABa3aOCACB
