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.
The complete program is to define a boolean method that returns true if all elements of an array are negative, or return false, if otherwise
The method in java, where comments are used to explain each line is as follows:
//This defines the method
public static boolean chkNegative (double[] myArr) {
//This initializes a boolean variable
boolean isNeg = true;
//This iterates through the array
for (int i = 0; i < myArr.length; i++) {
//If the array element is 0 or positive
if (myArr[i] >= 0) {
//Then the boolean variable is set to false
isNeg = false;
//And the loop is exited
break;
}
}
//This returns true or false
return isNeg;
}
