Why the rainbow is always a semicircle?
A rainbow appears as a semicircle due to the curvature of the Earth. When sunlight enters raindrops and is refracted and reflected back towards the observer, it forms a circular arc in the sky. Since the Earth's surface gets in the way, only a portion of this arc above the horizon is visible, resulting in the appearance of a semicircle.
Why are rainbows semicircle not other shapes?
A rainbow just appears as a semicircle but it is actually a complete circle. We just don't see the whole thing because the horizon gets in the way. Sometimes people on planes will see the entire circle with the shadow of the plane in the center. White light is made up of a mixture of all the different colors. Light takes the form of waves and all the different colors have a different wavelength. Red light has the longest wavelength (720 nm) while violet has the shortest (380 nm). These different wavelengths can be used to explain why you see all the different colors in the rainbow. When light hits water droplets in the air, it is bent slightly - this bending is called diffraction. The amount of diffraction depends on the wavelength - Red light is bent less than blue light so when white light meets the water droplets, it is separated into all the different colors. If you turn on a garden hose, adjust the nozzle to a fine spray and stand with your back to the sun, you will see a rainbow shining in the spray!
Can a rainbow be straight in the air?
No, rainbows are always curved in shape due to the way light is refracted and reflected in raindrops in the atmosphere. The arc of a rainbow will appear different depending on the observer's position relative to the sun and rain.
Is rainbow look full circle?
The would be if the ground didn't get in the way. If you're on a mountain or high ground looking into a valley, or looking down from an airplane, and the sun is high behind you and the air below you is full of water droplets, then you can see the full circle of the rainbow.
Why do you need rain to have rainbows?
Rainbows occur when sunlight is refracted, or bent, by water droplets in the air. This refraction splits the light into its different colors, creating the rainbow. Therefore, rain is needed to create the water droplets in the air that are necessary for the formation of a rainbow.

Why is the sky under a rainbow usually lighter than the sky around it?
The lighter sky under a rainbow is created by the way that light is bent inside raindrops. The raindrops also focus the sunlight into an expanse of bright light that illuminates the sky under the rainbow's arc.

What colors form a rainbow and what order are they in?
Red, Orange, Yellow, Green, Blue, Indigo and Violet are the colours of a rainbow visible to the human eye. These are the colours as originally stated by Newton. Infrared and ultraviolet can also appear at either end of a rainbow but these colours aren't visible to the human eye.
Why the color of the rainbow arranged in that way?
The colors of the rainbow are arranged in a specific order due to the way light is refracted and dispersed by water droplets in the atmosphere. This process separates the different wavelengths of light, creating the distinct bands of colors in the rainbow, with red appearing on the outer edge and violet on the inner edge. This order of colors is a result of the varying wavelengths of light being bent at different angles.
Why does a pencil appear bent in a cup of water?
When light travels from water to air, it changes speed and direction due to the change in medium, causing a refractive effect. This phenomenon makes the pencil appear bent at the water's surface due to the way light rays are bent as they pass through the boundary between water and air.
What is the best way to explode a rainbow?
There is no way you can explode a rainbow. You cant even touch it. It is just a reflection
Why do you only see an arch in a rainbow?
A rainbow appears as an arch due to the way light refracts, reflects, and disperses in water droplets in the atmosphere. When sunlight enters a droplet, it bends (refracts), reflects off the inside surface, and then bends again as it exits, creating a spectrum of colors. The circular shape of the rainbow is a result of the angle at which light exits the droplet, typically forming a semicircle. However, we usually only see the upper half of this circle because the ground obstructs the lower half.
