Can two rainbows appear in the sky at the same time?

Rainbow, also known as rainbow, is an optical phenomenon in meteorology. When the sun shines on the water droplets in the air, the light is refracted and reflected, forming an arched color spectrum in the sky, which is a common phenomenon after rain. Curved, usually semicircular. Rich and colorful. The most common sayings about seven-color light in East Asia and China (in descending order of wavelength) are red, orange, yellow, green, blue, indigo and purple. Many times, two rainbows will appear at the same time. Outside the ordinary rainbow, it is an optical phenomenon in meteorology to rotate the starry sky like a rainbow. When sunlight hits the raindrops in mid-air, the light is refracted and reflected, forming an arched color spectrum in the sky. Rainbow is a natural phenomenon, which is caused by the reflection and refraction of sunlight when it hits water droplets in the air. A concentric but dark secondary rainbow (also known as "neon") appears. The secondary rainbow is formed by two reflections of sunlight in water droplets. When sunlight passes through water droplets, it will be refracted, reflected and then refracted again. Ordinary rainbow (main rainbow) is formed after light is reflected in water droplets. If light is reflected twice in a water drop, a second rainbow (neon) will be produced. The color arrangement of neon is opposite to that of the main rainbow. Because every reflection will lose some light energy, the brightness of neon lights is also very weak. The strongest reflection angle of the two reflections occurs at 50 to 53, so the position of the secondary rainbow is outside the main rainbow. Because there are two reflections, the color sequence of the auxiliary rainbow is opposite to that of the main rainbow, with the outer side being blue and the inner side being red. In fact, the auxiliary rainbow must follow the main rainbow, but sometimes it is invisible to the naked eye because of the low light intensity. Sunset is a rare phenomenon, which may appear in the night with strong moonlight. Because it is difficult for human vision to distinguish colors in low light at night, the night rainbow looks as if it is all white.
