The behavior of light makes it
possible for you to see a spectrum of colors in a spray of water on a sunny day
is refraction. The refractive index of a medium is dependent on the wavelength
and hence light of different wavelength undergo refraction by different angle
which causes the splitting of light beam in different color.
To solve the problem it is necessary to apply the concepts related to Chvorinov's Law, which states that
Where,
= Volume cube
= Superficial Area from Cube
= Volume Rectangle
= Superficial Area from Rectangle
Our values are given as (I will try to develop the problem in English units for ease of calculations),
Applying the Chvorinov equation we have to,
The stipulated time for the cube is 14.5 then,
He did sadly can’t believe it T-T
The Earth's gravitational pull and the table's force are of equal magnitude and in opposite directions, they balance each other.
<u>Explanation:</u>
A book placed on a surface have two forces acting on it which are, a force that pulls it toward the ground in a downward direction, that is gravitational pull and a second which is acted on the book on upward direction making a balance on the object.
This follows Newton’s third law of motion that states every action has an equal and opposite reaction.
