RAINBOW- Anti mony explains

 Those bright color you see most after after a heavy rainfall. And you were told a lot of fairy tales about them. I will explain here so you will gain knowledge.

 A rainbow is a multicolored arc made by light striking water droplets.

Are you grabbing🤗

The most familiar type rainbow is produced when sunlight strikes raindrops in front of a viewer at a precise angle (42 degrees). Rainbows can also be viewed around fog, sea spray, or waterfalls. 

A rainbow is an optical illusion—it does not actually exist in a specific spot in the sky. The appearance of a rainbow depends on where you're standing and where the sun (or other source of light) is shining.

The sun or other source of light is usually behind the person seeing the rainbow. In fact, the center of a primary rainbow is the antisolar point, the imaginary point exactly opposite the sun.

I hope my vocabularies are understandable😐😐😐

Rainbows are the result of the refraction and reflection of light. Both refraction and reflection are phenomena that involve a change in a wave's direction. A refracted wave may appear "bent," while a reflected wave might seem to "bounce back" from a surface or other wavefront.

 As you were taught in your class physics. I hope you remembered☺

Light entering a water droplet is refracted. It is then reflected by the back of the droplet. As this reflected light leaves the droplet, it is refracted again, at multiple angles.

The radius of a rainbow is determined by the water droplets' refractive index. A refractive index is the measure of how much a ray of light refracts (bends) as it passes from one medium to another—from air to water, for example. A droplet with a high refractive index will help produce a rainbow with a smaller radius. Saltwater has a higher refractive index than freshwater, for instance, so rainbows formed by sea spray will be smaller than rainbows formed by rain.

Rainbows are actually full circles. The antisolar point is the center of the circle. Viewers in aircraft can sometimes see these circular rainbows.

Viewers on the ground can only see the light reflected by raindrops above the horizon. Because each person's horizon is a little different, no one actually sees a full rainbow from the ground. In fact, no one sees the same rainbow—each person has a different antisolar point, each person has a different horizon. Someone who appears below or near the "end" of a rainbow to one viewer will see another rainbow, extending from his or her own horizon.

Colors

A rainbow shows up as a spectrum of light: a band of familiar colors that include red, orange, yellow, green, blue, and violet. The name "Roy G. Biv" is an easy way to remember the colors of the rainbow, and the order in which they appear: red, orange, yellow, green, blue, indigo, and violet. (Many scientists, however, think "indigo" is too close to blue to be truly distinguishable.)

White light is how our eyes perceive all the colors of the rainbow mixed together. Sunlight appears white. 

When sunlight hits a rain droplet, some of the light is reflected. The electromagnetic spectrum is made of light with many different wavelengths, and each is reflected at a different angle. Thus, spectrum is separated, producing a rainbow.

Red has the longest wavelength of visible light, about 650 nanometers. It usually appears on the outer part of a rainbow's arch. Violet has the shortest wavelength (about 400 nanometers) and it usually appears on the inner arch of the rainbow.

At their edges, the colors of a rainbow actually overlap. This produces a sheen of "white" light, making the inside of a rainbow much brighter than the outside.

Visible light is only part of a rainbow. Infrared radiation exists just beyond visible red light, while ultraviolet is just beyond violet. There are also radio waves (beyond infrared), x-rays (beyond ultraviolet), and gamma radiation (beyond x-rays). Scientists use an instrument called a spectrometer to study these invisible parts of the rainbow.

CELLS-Antimony explains😊

  What is cell? Maybe you have heard of that word before..🤔   Cell is the basic building blocks of all living things.😋  intresting right?.  The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves.😊😐 Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell. Human cells contain the following major parts which am going to list in alphabetical order: Cytoplasm Within cells, the cytoplasm is made up of a jelly-like fluid (called the cytosol) and other structures that surround the nucleus. Cytoskeleton The cytoskeleton is a network of long fibers that make up the cell’s structural framework. The cytoskeleton has several critical functions, including determining cell s

(0.6)HISTORY OF ATOM- Antimony explains

Ohh. Now in 1920 this Scientist;Erwin Schrödinger vex and scatter everywhere with his new hypothesis.🤓 Erwin Schrödinger was a revolutionary physicist who used Heisenberg’s  uncertainty principle to come up with the atomic model that we still use today. SCHRÖDINGER’S ATOMIC MODEL (AKA THE CLOUD MODEL)  After doing a lot of work he concluded these salient points am going to alight now. They include: 1. An electron does not travel in an exact orbit😗 2. We can predict where it will probably be😙 3. We cannot say for certain where it is, but only where it ought to be.😚 4. The type of probability orbit is dependent on the energy level described by Bohr☺ Let's now summarize what we know of atoms. The smallest part of an element is called an atom Each atom (of an element) is different in structure from  other atoms (of other elements) An atom can be divided in smaller subatomic particles: Protons, Electrons and Neutrons The nucleus is the centre of an atom. It contains protons and neut

WHY THE SKY IS BLUE-Antimony explains

  Antimony-Explains Why is the sky blue? It’s a common misconception that the sky is blue because it reflects the blue of the seas and oceans. A lot of myths have also been told about our blue sky😉. That is why Antimony is here for you. To debunk those non relevant ideas.😊 As for the seas reflection it is very wrong. In fact, it’s the Earth’s atmosphere, and a process known as 'scattering', that causes our skies to be blue.   So what is this scattering. As white light passes through our atmosphere, tiny air molecules cause it to ‘scatter’. The scattering caused by these tiny air molecules (known as Rayleigh scattering) increases as the wavelength of light decreases. Violet and blue light have the shortest wavelengths and red light has the longest. Therefore, blue light is scattered more than red light and the sky appears blue during the day. When the Sun is low in the sky during sunrise and sunset, the light has to travel further through the Earth’s atmosphere. We don’t see t
