These waves are traveling at the same speed. which wave has the highest frequency?

A

Explanation: The relation between velocity and frequency of the waves is:

f = v/λ

where f is frequency, v is the velocity and λ is the wavelenght.

So you can see that, if the 4 waves have the same velocity, then the one with the smallest wavelenght (because it is in the denominator) will have the highest frequency.

The one with the smallest frequency is the first one (you can see it) so the correct option will be A

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
