Question

A plant with green leaves & red flowers is placed in :-a) Green ; b) red ; c) Blue light. What color will the leaves & flowers appear in each case? Assume all the colors are pure.

Answer 1

a).only leaves will show color flower will tend to be dark.
b).only flower will show up leaves will tend to be dark.
c). both leaves and flowers will be dark.
(any object which has a color absorbs rest of colors of spectrum except that color which it reflects
for example: green leaves absorbed v.i.b.y.o.r. except green which is reflected by leaves)
so if placed in red light they will not show any color because leaves will absorb red color)
