Byron draws a ray diagram to show how an image is produced by a lens.

A flower is the object in front of a biconcave lens and is farther than 2 F from the lens. A ray parallel to the principal axis is labeled X and bent away from F. A second light ray toward F on the image side of the lens is bent parallel to the principal axis is labeled Y. The image is closer to the lens than F on the object side of the lens, is the same size as the object and erect.

Which describes Byron’s error?

A. The image should be smaller than the object

Explanation:

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
