Ray R1& R2 are both parallel to principal axis hit the mirror as shown. If R1& R2 intersect principal axis at points P1& P2 respectively then :
A
Both P1& P2 are at Focus
B
Distance of P1 from focus is more than distance of P2 from focus
C
Distance of P2 from focus is more then distance of P1 from focus
D
P1& P2 are on the two sides of focus
Answer
Distance of P1 from focus is more than distance of P2 from focus
