Question

The beautiful natural phenomenon of the rainbow is a combination of which of the following different phenomena?
A) Refraction, reflection
B) Dispersion, refraction
C) Refraction, dispersion, reflection
D) Reflection, dispersion

Answer 1

Hint: A rainbow is a natural spectrum of sunlight in the rainbow that appears in the sky when the sun shines on the raindrops. This effect is due to the combination of internal reflection and dispersive reflection in rainwater.

Complete solution:
Rainbows are caused by rain that separates the white cloud into its colored parts. Some lights fall on a drop of water that falls on a droplet, and once inside the droplet, the color of the sunlight changes to various degrees, depending on each one. wavelength. The rainbow is the seven-colored VIBGYOR line we usually see during the rainy season. This results in the dissemination, reflection and updating of knowledge.
Rainbows are visual representations and weather forecasts caused by looking backward, circulating light and scattering it into water droplets, resulting in the formation of lines in the sky. It looks like a multicolored bow. Rainbows caused by sunlight usually appear in the part of the sky, directly opposite the sun.
As we know, a rainbow is the result of reflection, refraction and scattering of light in water droplets, but a rainbow has only seven colors. White sunlight illuminates the human eye and there is an invisible spectrum above red (infrared) or violet (ultraviolet). The seven visible colors are a part of it.

Hence option C is correct.

Additional Information:
Rainbows are shaped like a full circle, not everyone believes it is an arc. Because the rainbow represents the spherical shape of the sun. If you take a plane or use a drone, you will see a round rainbow from the sky. When the audience sees the rainbow on the ground, they see the top of the horizon, Rainbow is seen on the other side of the sky in the sun, it is clearer than the rainbow, and it is closer to the horizon.

Note: There is only one sun in the sky, but sometimes we see a double rainbow. This implies that as a result, the spectrum of the secondary rainbow is compared to the primary, red inside and purple outside.
