One doesn't have to be at any specific angle to see a rainbow. What is Dependent on seeing the rainbow is the location of the rain, and sun relative to you. The sun is always behind a rainbow when seen. So you would be in front of the rainbow, rain, and the sun. Also, No two people see the same rainbow unless a picture or video was taken of the rainbow.

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.
What does angle b always says to annoy angle a and c?
A! i cant see
What are the colors of the rainbow and how many colors?
Red, orange, yellow, green, blue, violet, indigo . Seven(7) colours. NB When observing a rainbow in the sky;- Red is always on the outside of the bow. Inigo(blue) is always on the inside of the bow. Outside the red arc, the sky is darker, (light bending) Inside the indigo arc, the sky is lighter, (light bending again). When observing a rainbow, the centre of the rainbow is in a direct line between the Sun(at your back), you and the rainbow centre. NNB The angle from the centre line of the rainbow to the arc is 42 degrees. NNNB A very bright rainbow will produce a reflected rainbow outside the primary rainbow; the colours are reversed.
Why the rainbow is semi circle in shape?
Actually it is circular but usually the sun needs to be quite low in the sky for the angle of the sunbeams hitting the raindrops to be suitable to create a rainbow visible from the ground. But, when that happens, a part of the rainbow is cut-off by the horizon and so it appears semicircular. Full circles are rare but have been seen/photographed.
What is the measure of the unknow angle?
See a right angle is 90 degrees. An acute angle is less than 90 degres. A obtuse angle is more than 90 degrees.
Why is it possible to see a circular rainbow when your in an airplane yet its impossible from the ground?
Its actually depends what angle you are looking at the rainbow. On the ground you might be seeing a regular rainbow but from the sky you are seeing a circle.
How does light and rain make a rainbow?
The moisture droplets in the air refract the light like a prism. This happens with millions of droplets, and depending on the angle at which you observe it, you see a rainbow.
What angle does it take for these colors to form in a Rainbow?
40 cm angle
Why the rainbow is always a semicircle?
becaz the critical angle of rainbow is so large......
What is the angle of red colour in rainbow?
90
Why might you only see a rainbow when rain is in front of you?
Because the angle of the Sun in relation to the viewer must be within a specific range.
How come when you get close to rainbow it seem as if it further back?
The rainbow is an optical effect caused by the angle at which the sunlight hits the water droplets in the air. As you move, this angle remains the same, so the rainbow appears to move.
Why is the rainbow curved?
A rainbow is curved due to angle requirements. Light from the sun that bounces through a drop of water, comes into your eye, and appears red must bounce at a specific angle. Join two sticks together at a set angle. Place one end at a dot to represent the sun. Place the other toward your eye. The place where the sticks join, where the water drop is, can be rotated around in a circle. A rainbow is shaped like a circle. You never see the entire rainbow because of the horizon. When you look at a rainbow, the Earth gets in the way of most of the circle. The portion you see is just the top portion. Draw a circle and cover a little more than half of it. What is left is the shape of a rainbow.
Can you make a rainbow with a right angle prism?
Yes.
Which chemicals make a rainbow?
A rainbow is formed as a full visible spectrum, where there is a completely graded system of particle size, or of viewing angle. The common airborne rainbow is composed of water droplets, which, depending on the observers angle, span the full visible spectrum. You may also see a rainbow of colour on the surface of a CD, where the grooves form a diffraction grating. Another different rainbow is formed when a thin film of one liquid is spread out over another fluid - without mixing. This is your common gasoline rainbow on a puddle. Back in the day when film transparencies were commonly mounted in glass covers, then 'Newton's Rings' of a rainbow may show as the angle between the media change. And of course, a rainbow is formed when white light passes through a prism - the chandelier and the diamond ring are examples. So, the phenomenon is one of angle, not particularly of chemical nature.
Why rainbow is round?
Because from every point on the rainbow, the angle between the direction to thesun and the direction to your eye has to be the same angle. The only collectionof points that can do that is all the points on a circle.
Is there an experiment to show that light passes though glass?
yes get a piece of glass or crystal and hold it in the sunlight. get the right angle so you can see a rainbow inside the glass/ crystal. it shows how light is actually all colours of the rainbow, however you can only see what it reflects.
