The correct answer is **Option E – No correct option**. When a red object, such as a rose, is observed under blue light, it appears black. This is because the red rose absorbs blue light and has no red light to reflect, making it appear black in color. Although a mixture of red light and blue light would result in magenta, this is not the case here since we are only using blue light to observe the rose.
Oga the answer is Magenta.C, the question they ask is light not paint, Red light + Blue light = Margenta, while Red paint + Blue paint = Pupple.
Oga the answer is Magenta, this is light not paint. Red light + Blue light = Magenta
R+G= Y, B+G= Cyan. For paint R+Y= Orange, Red+Blue= Pupple, B+G=G. Oga the question they ask is red rose observe in a Blue LIGHT, light not paint. The answer is Margenta.
