Which color of light has a wavelength of 5.0x10^-7 meters in air?
1 answer:
Green light.
In fact, wavelength of
corresponds to 500 nm. The spectrum of visible light goes from approximately 380 nm (corresponding to violet light) to 750 nm (corresponding to red light). Green is approximately in the middle, having a wavelength range between 495-570 nm, therefore 500 nm lies in this range.
In fact, wavelength of

assuming north-south along the Y-axis and east-west along the X-axis
X = total X-displacement
from the graph , total displacement along X-direction is given as
X = 0 - 20 + 60 Cos45 + 0
X = 42.42 - 20
X = 22.42 m
Y = total Y- displacement
from the graph , total displacement along Y-direction is given as
Y = 40 + 0 + 60 Sin45 + 50
Y = 90 + 42.42
Y = 132.42 m
magnitude of the net displacement vector using Pythagorean theorem is given as
magnitude : Sqrt(X² + Y²) = Sqrt(22.42² + 132.42²) = 134.31 m
Direction : tan⁻¹(Y/X) = tan⁻¹(132.42/22.42) = 80.4 deg north of east
