Verified step by step guidance

Understand the function of rods and cones in the human eye: Rods are responsible for vision in low light conditions and are more sensitive to light, while cones are responsible for color vision and function best in bright light.

Recognize that frequency in this context refers to the wavelength of light, which is inversely related to frequency. Higher frequency corresponds to shorter wavelengths (e.g., blue light), and lower frequency corresponds to longer wavelengths (e.g., red light).

Identify that rods are more sensitive to light at the lower end of the visible spectrum, which corresponds to longer wavelengths and lower frequencies.

Cones, on the other hand, are sensitive to different ranges of wavelengths, with some cones being more sensitive to higher frequencies (shorter wavelengths) such as blue light.

Conclude that rods have their peak sensitivity at a lower frequency compared to cones, which are more sensitive to higher frequencies.
