Since rods are about 1000 times more sensitive than cones (at 500 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 correct?
a. rods are able to detect electric fields 1000 times smaller than the fields detectable by cones.
b. rods are able to detect electric fields 1000/3=333 times smaller than the fields detectable by cones.
c. rods are able to detect electric fields 1000√=32 times smaller than the fields detectable by cones.
d. rods are able to detect electric fields 3 times smaller than the fields detectable by cones.
