Question

At high levels of illumination, the rods and cones both function and the eye is most sensitive to light wavelengths around 550nm. This effect is called:

A)
Photopic vision

B)
Prkinje effect

C)
Scotopic vision

D)
Incandescent effect

Answer 1

The effect described in the question is called photopic vision. It refers to the vision in bright light conditions when both the rods and cones in the eyes are functioning. Cones are responsible for color vision and are most sensitive to light wavelengths around 550nm.

Step-by-step explanation:

The effect described in the question is called photopic vision.

Photopic vision refers to the vision in bright light conditions when both the rods and cones in the eyes are functioning.

Cones are responsible for color vision and are most sensitive to light wavelengths around 550nm.

This is why humans perceive light in its full color range under bright illumination.

On the other hand, scotopic vision is the term used for the vision in low light conditions where only the rods are active.
