Given the distance between the crest of one wave and the crest of the next wave, you can determine the wavelength. amplitude. frequency. equilibrium.

Wavelength

Explanation:

The distance between the crest of one wave and the crest of the next wave is called wavelength of a wave. It is denoted by lambda λ. The maximum displacement of the particle of a wave is called amplitude of wave. The topmost value of displacement of the wave is called crest of a wave while the lowermost value of displacement of the wave is called trough of the wave.

Hence, by finding the distance between the crest of one wave and the crest of the next wave, we can determine the wavelength of a wave.

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
