Accepted Answer

Blue cones

Question 3

Which structure of the eye is primarily responsible for changing shape to focus images at different distances?

Accepted Answer

Lens

Question 4

According to the trichromatic theory, how many types of cones are there, and what are they sensitive to?

Accepted Answer

Three types; sensitive to different wavelengths

Question 5

Which of the following correctly matches the wave property with the perceived property?

A person notices that after staring at a green image for a long time, they see a red afterimage when looking away. Which theory best explains this phenomenon?

Accepted Answer

Opponent process theory

Question 7

Which part of the eye contains the highest concentration of cones and is responsible for sharp central vision?

Accepted Answer

Fovea

Question 8

As people age, they often need reading glasses due to a loss of accommodation. Which structure is most affected?

Accepted Answer

Lens

Question 9

Which cells in the retina are responsible for night vision and are more sensitive to low light?

Accepted Answer

Rods

Question 10

What is the correct order in which light passes through the eye structures before being converted to a neural signal?

Accepted Answer

Cornea → Lens → Retina

Which phenomenon is explained by opponent process theory but not by trichromatic theory?

Accepted Answer

Afterimages

Question 12

If a person has a blind spot in their vision, what is the anatomical reason for this?

Accepted Answer

Accepted Answer

Rods

Question 15

Which theory of color vision states that color perception is based on three types of cones, each sensitive to a different range of wavelengths?

Accepted Answer

Trichromatic theory

Question 16

If the amplitude of a light wave increases, which perceptual property will be most affected?

Accepted Answer

Brightness

Question 17
