A rainbow can be seen when the sun is at around 42 degrees above the horizon. This angle allows sunlight to be refracted and reflected within raindrops to create the phenomenon of a rainbow.

How many degrees above the horizon does the upper edge of a rainbow usually reach?

The altitude of the highest point of the rainbow that you see is (42 degrees) minus (the altitude of the sun above the horizon behind you). If the sun is sitting right on the horizon ... just risen or just about to set ... then the highest point of the rainbow is about 42 degrees above the horizon opposite the sun. If the sun is higher, then the rainbow is lower, by the same amount. If the sun is more than about 42 degrees above the horizon, then any rainbow you might otherwise see is entirely below the opposite horizon, and you don't see one.


What is the angle of the sun so that a rainbow can form?

Rainbows are formed through refraction. The refraction happens through the rain drops, causing the light (which is made up of a spectrum of colours) to split and causes a rainbow.

What does rainbow in the morning gives you fair warning mean?

The phrase "rainbow in the morning gives you fair warning" is a weather folklore saying that warns of potential bad weather, such as storms, that may be incoming later in the day. It's based on the idea that rainbows are often seen in the morning due to the angle of the sunlight, which can be a precursor to unsettled weather.


How big is a rainbow?

A rainbow is a circular arc of light that forms when sunlight interacts with raindrops in the atmosphere. The size of a rainbow can vary, but they are typically seen as a semicircle with a diameter of around 42 degrees centered on the antisolar point.


What direction is a rainbow if the sun is setting?

If the sun is setting, the rainbow would be in the opposite direction in the sky, typically in the eastern part of the sky. This is because rainbows form when sunlight is refracted, reflected, and dispersed by raindrops in the atmosphere, creating a colorful arc opposite the sun's position.

Is a rainbow a bow or a circle?

A rainbow is a circle. What we see from almost any point on earth is a semicircle, or just a part of the rainbow. We can only see it from horizon to horizon, or just an arc of the whole rainbow. Occasionally we can see a full circle of a rainbow in the sky surrounding the sun, and sometimes multiple ones.


Is their really somthing at the end of a rainbow?

No. This is because there is no "end of a rainbow". A rainbow is actually circular, but it's just that the horizon hides the lower half.


In Which direction rainbow appears in morning?

A rainbow must always be in the opposite direction from you compared to the sun.So if you see a rainbow in the morning, its center would be in a generally westerlydirection from you.

Does the rainbow happen because of a storm?

Yes, but only at certain times of the day and the raindrops have to be a certain size. The sun has to hit the tiny drops of water at just the right angle to create a rainbow. In order for this to happen, the sun has to be at a certain point in the sky, like in early morning, or late afternoon. If the sun is too high in the sky, no rainbow. The storm has to be in front of you and the sun has to be behind you.

Why cannot you see a rainbow at noon?

Rainbows usually form when sunlight is refracted and reflected off water droplets in the atmosphere, creating the spectrum of colors. At noon, the sun is directly overhead, so the angle at which sunlight hits the water droplets is not conducive for rainbow formation. The sunlight needs to hit the droplets at a specific angle to create a rainbow, which is why they are typically observed early in the morning or late in the afternoon.


When do rainbows occur?

whenever there are water droplets in the air and the sun is shining through them at a low angle. This angle is 40 - 42 degrees from the observers head. If the sun is any higher the rainbow effect will not be seen as the rainbow will be below the horizon. Secondary rainbows can occur at about 50 degrees, but the colours will be inverted


What is the meaning of rainbow upon seeing in in the morning?

The meaning is that there is rain or heavy mist in the air to the west of you, and the sky east of you, where the sun is located, is clear. Also, if you are witnessing a rainbow in the morning, then you are most likely facing to the west.
