How does a concave mirror form an image? it bends the light toward a focal point. it bends the light away from a focal point. it bounces the light toward a focal point. it bounces the light away from a focal point.

It bounces the light toward a focal point.

Explanation:

When light incident on the mirror it is reflected as per the law of reflection. As per law of reflection angle of incidence must be equal to the angle of reflection with respect to normal.

When light incident parallel to principle axis of the concave mirror then it travels to in such a way that after reflect it will bend towards the focus of the mirror

so we can say

so here we know light is coming parallel to principle axis so object distance is infinite here

so image position is focal length of mirror

so correct answer is

It bounces the light toward a focal point.

the part of the wave he is travelling on is the crest

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
