Question

Since rods are about 1000 times more sensitive than cones (at 470 nm), they should be able to detect smaller values of the electric field. Assuming rods and cones are sensitive to the average energy density of an electromagnetic wave, which of the following statements is the most accurate?a. Rods are about 1000 times more sensitive than cones.b. Rods are about 3 times more sensitive than cones.c. Rods and cones are about equally sensitive.d. Cones are about 3 times more sensitive than rods.e. Cones are about 1000 times more sensitive than rods.

Answer 1

a. Rods are about 1000 times more sensitive than cones.
