Question

the angle between the paraxial rays and the principal axis is...???​

Answer 1

Answer:

30*

Explanation:

The rays parallel and close to the principal axis are called paraxial rays. It forms a small angle Q due to its area present between. A/to my understanding its evenly distributed so I say its 30*

Answer 2

To find:

Angle between paraxial rays and principal axis ?

Solution:

First of all , let's define the terms :

PRINCIPAL AXIS:

• It is an imaginary line passing through the Centre of Curvature , Focus and Pole of the spherical mirror.

• We often see the object being placed on the Principal Axis considering it to be a reference.

PARAXIAL RAYS:

• Paraxial rays are rays originating from objects placed at infinity , but these rays are parallel and close to the principal axis.

Now , in the definition the word "PARALLEL" has been used.

So, the angle angle between Principal Axis and Paraxial rays will be zero degree (0°).
