With your back to the Sun, you will see the full arc of a rainbow.
An imaginary line from the Sun , through you, will take you to the centre of the rainbow.
From that line to the centre of the rainbow, to the coloured arc is an angle of 42 degrees.
The primary rainbow's colours, from the outside are rea, orange, yellow, green, blue violet, indigo to the inside of the rainbow. Since red light has a longer wavelength than blue light, then the red arc is longer , on the outside of the r'bow. Conversely the blue light is a shorter wavelength so it is seen on the inside/shorter side of the bow. If the light is very strong/bright, then you ,may see a secondary rainbow out side the primary rainbow. The colours are reversed in the secondary rainbow. Very rarely you may see tertiary rainbow, outside the secondary rainbow and the colours are reversed again.
Also because of natural bending of light the outside of the red edge is dark and the inside of the blue edge is light.
You only see a rainbow if rain is falling and the sun is shining in different part of the sky.
The old weather lore in England, A rainbow in the morning foretells bad weather, the day.
A rainbow in the evening and the bad weather is going away for the rest of the day. In fact it is more reliable than Red Sun morning or evening.
Depends when the rain ends
Rainbows are optical and meteorological phenomena that occur when sunlight is reflected, refracted, and dispersed in droplets of water. Since they are dependent on sunlight and water droplets, there is not a set number of rainbows in the world at any given time. They can appear wherever light and rain interact in the right conditions.
Reading your question is the first time I've heard the suggestion that they're disappearing, and I'm very skeptical. If they are, then it can only be the result of decreasaing transparency of the atmosphere. A shorter way to say that is 'Air Pollution'.
Rainbows are most likely to occur in the late afternoon as the sun is low in the sky, and after a rain shower when the sun starts to come out. The sun's angle at this time allows the light to be refracted and reflected in the raindrops, creating a rainbow in the sky.
Rainbows are typically seen in the western part of the sky in the afternoon. This is because the sun is in the western part of the sky during that time, and rainbows form when sunlight is refracted and reflected off water droplets in the air.

Rainbows are a result of sunlight being reflected, refracted, and dispersed through raindrops in the atmosphere. They appear for a short time because the angle and position of the sun, as well as the location of the observer, need to be just right for the optical effects to create a rainbow. Once these conditions change, the rainbow disappears.
Harry does most of time and also Liam
A rainbow can occur whenever there are raindrops and sunlight at the same time. They are most commonly seen after a rainfall when the sun breaks through the clouds. The frequency of rainbows depends on weather conditions and location.
Rainbows can be seen when there is sunlight and rain simultaneously. Typically you can see rainbows when the sun is low in the sky, so early morning or late afternoon are the best times to see rainbows.
purple rainbows and sunshine
They like to worship unicorns and eat rainbows
They could. but most of them are from when you were born.
