Answer:

a) False

b) True

c) True

d) False

e) False

f) True

Step-by-step explanation:

a) False - The size of the retina does not determine the amount of light entering the eye; the size of the pupil does.

b) True - Compound eyes are found in many insects and crustaceans, and consist of multiple lenses that allow them to detect motion and form a wide field of view.

c) True - Prolonged exposure to ultraviolet (UV) light can be harmful to the eyesight and can cause cataracts and other eye disorders.

d) False - The angle of incidence and the angle of refraction are not always equal; they are generally different except in the special case of light passing from one medium to another with the same refractive index.

e) False - The term "color blind" is more appropriate than "color defected", and people with color blindness have difficulty distinguishing between certain colors but can still see colors.

f) True - Concave mirrors are curved inward and can create magnified or reduced images depending on the position of the object and the observer relative to the mirror.
