An angle
A ray is a line that begins at a point and goes away from it forever and ever.If two of these rays share the same starting point, it is called a vertex.What figure would look like a point with 2 rays going in different directions be called?You're looking at an angle.
an angle
Yes. Any two rays which have the same end point.
a rainbow 
No, they are different!
angle
Yes, numerous rays can have the same point.
all it is, is two rays in the same line that end with the same endpoint
Two rays starting at the same point of origin form an angle

The speed of beta rays emitted by the same element can vary because the energy of the emitted beta particles is not constant. The speed of beta particles depends on the energy released during the decay process and may be influenced by factors such as the type of decay (beta-minus or beta-plus) and the initial energy state of the nucleus.
an angle
Yes. Any two rays which have the same end point.
An angle is formed when two rays begin at a common point. The common point is called the vertex of the angle.
