Some Most Important Facts Relating To Science, Which You Should Know.


Why does the size of the Sun appear much larger and red than the normal size at the time of rise and fall?

This is due to the radiation theory of light. Blue rays are radiated by air particles from the white light of the sun passing through the atmosphere near the horizon. While the red rays are the lowest radiation, the sun appears red. The change in the shape of the sun comes from atmospheric pressure. As the amount of change increases as height decreases, the vertical becomes smaller while the horizon floor increases. Therefore, the sun is visible near the horizon. That is, the sun appears big at sunrise and sunset.

A piece of ice is transparent but its 'sawdust' becomes opaque after grinding it, why?

When white light falls on a piece of ice, it is reflected back by its millions of tiny particles. Since light is not absorbed by the dust of ice, it is opaque.

Why is there a difference in the color of the light of a bulb and the color of light of a tube light.

Why do plants wither when more fertilizer is applied in the fields?

The water present in the root follicles of the roots is more dilute than the solution of mineral salts. So water enters the original Romans from the ground by osmosis. By using more fertilizers in the fields, the land solution will be thicker than the original follicles. As a result, it will begin to move water from the original follicles to the land by osmosis, so plants start to fade when they put more fertilizer in the fields.

Which shrinks and spreads as the temperature rises and decreases. These cells change color by being stimulated by some hormones secreted in their body. These hormones are intermedine acetyl choline and adrenaline. The cells of the upper surface of the skin are yellow, dark brown and black below it, and white at the bottom. Due to the decrease in temperature, their color becomes darker and the color starts becoming lighter due to increasing temperature. Reptiles that roam at night have an opposite reaction. Sexual and emotional state also have an effect on their color, reptiles climbing trees or inhabiting them have a tendency to change color. It turns green, yellow, brown and gray.
