Which part of the electromagnetic spectrum has a lower frequency than visible light?

ultraviolet

x-rays

gamma rays

infrared

The Correct Answer is D.Infrared/ INFARED has a lower frequency than visible light/

Ultraviolet part of the electromagnetic spectrum has higher frequency than the visible light.

X-ray part of the electromagnetic spectrum has higher frequency than the visible light.

gamma rays part of the electromagnetic spectrum has higher frequency than the visible light.

infrared red part of the electromagnetic spectrum has lower frequency than the visible light.

hence the correct choice is infrared

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
