Answer:
Reflection
Explanation:
Reflection is the property of light in which when a ray of light hits a smooth surface, it bounces back in the direction in which it came from. If i is the angle between the normal to the surface and the incident ray, and r is the angle between the normal and reflected ray, the law of reflection states that the angle of incidence equals the angle of reflection. That is, i = r.
So, to record the image of an object with a camera, one property of light that makes that possible is reflection because, the incidence rays form an image of the object in the camera, while the reflected rays reflect the image so that it is visible to the eye.

Answer:
The answer to this question is given below in the explanation section.
Explanation:
The iteration variable begins counting with 0 or 1.
As you know the iteration mostly done in the looping. For example, for loop and foreach loop and while loop, etc.
It depends upon you that from where you can begin the counting. You can begin counting either from zero or from one.
For example: this program counts 0 to 9.
<em>int total=0;</em>
<em>for(int i=0; i>10;i++)</em>
<em>{</em>
<em>total = total+i;</em>
<em>}</em>
Let's suppose, if you want to begin counting from 1, then the loop should look like below:
<em>int total=0;</em>
<em>for(int i=1; i>10;i++)</em>
<em>{</em>
<em>total = total+i;</em>
<em>}</em>
