Question

What are the color receptors in your eyes perceiving if you see a white building?

        A) All of the color receptors in your eyes are equally stimulated when you see the

        color white.

        B) Only cones are stimulated in your eyes when you see the color white.

        C) Only the rods are stimulated in your eyes when you see the color white.

        D) No color receptors are stimulated when you see the color white.

Answer 1

Answer-

According to the given question-

• Rods and Cones are celled photoreceptors present in our eye.
• Rods are rod shaped, present in the retina boundary , approximately 100 million in numbers and responsible for twilight vision or scotopic vision and cones are cones shaped, present in centre part of retina, approximately 6 million in number and   responsible for day vision or when we see bright light or photopic vision.
• Cones after stimulation due to light immediately send signals to brain, which work as colour interpreter. There are three types of cones such as green, blue and red are found but when they are stimulated equally we observe white light
• Rods are capable of observing light intensity difference and can detect white, black, as well as gray shades.

So correct answer is (A) All of the color receptors in your eyes are equally stimulated when you see the color white.
