Answer:
There is a dependency relationship between the refractive index of each substance and the radiation wavelength.
The refractive index in a given medium is inversely proportional to the wavelength of a color.
For example:
The rays of the red color have a wavelength greater than the rays of the blue color, therefore they have a lower refractive index and consequently a light scattering less than the blue.
Snell's law :
n₂/n₁ = v₁/v₂ = λ₁ /λ₂
*n: (refractive index)
v: (speed of light propagation)
λ: (wavelength)
Double
Explanation:
Since the period T of a pendulum is given by
By increasing the length of the pendulum by 4, the period becomes
You can see that the period doubles when we increase the length by a factor of 4.
SPEED is distance divided by the change in time.
Force is change in momentum divided by the change in time.
Acceleration is change in velocity divided by the change in time.
Displacement is the straight-line distance and direction from the start-point to the end-point.
