Chapter 12, Problem 35R

To determine

the type of cells in the eyes which allows to see violet light among the options such as (A) red cones (B) green cones (C) blue cones (D) rods.

Answer to Problem 35R

The correct option is (C).

Explanation of Solution

Introduction:

Cones are present in the eyes which are responsible for perceiving colors of object to the eyes. The cones normally respond to the primary colors blue, green and red in order of their frequencies. They respond to the other frequencies in a lesser amount.

For violet, there is low response from the blue and almost none from the green and red. The blue color has the shortest wavelength and the blue cones are sensitive to a range of color wavelengths which includes the violet color. Thus violet color activates the blue cones

Conclusion:

Hence, the correct answer is (C).
