Chapter 26

Question 1

Image Formation and the Eye

Answer 1

Cornea and lens of an eye act together to form images (through refraction) on the retina

Light rays passing through the cornea produce an inverted, real image on the retina

Question 2

Microscope

Answer 2

Made from 2 converging lenses

First image is the object for the second lens

Final image is INVERTED, MAGNIFIED, and FAR from the observer (eye focuses easier on distant objects)

Question 3

Telescope (Refracting)

Answer 3

Collects more light

1 converging lenses + 1 diverging lenses = UPRIGHT image

2 converging lenses = INVERSE image

Question 4

Combining Thin Lenses

Answer 4

M=M1xM2

Question 5

Spherical Aberrations (Convex)

Answer 5

REFLECTED RAYS intersect at different points on the principal axis
