Answer:
A. f/2.8
Explanation:
A hole within a lens, through which light travels into the camera body is referred to as the APERTURE.
It is typically expressed as "f number" in photography. Basically, a fast lens is any lens with a maximum aperture of f/4 or more i.e f/2.8 , f/1.8 , f/1.4 etc.
The smaller the number is the bigger the maximum aperture is. Hence, the bigger the maximum aperture the more light that your lens will allow in.
Therefore, the ideal aperture settings for a fast lens is f/2.8
Answer:
import java.util.Scanner;
public class DashLine {
public static void main(String[] args) {
// Declaring variables
int n;
/*
* Creating an Scanner class object which is used to get the inputs
* entered by the user
*/
Scanner sc = new Scanner(System.in);
// Getting the input entered by the user
System.out.print("Enter a number :");
n = sc.nextInt();
// calling the method by passing the user entered input as argument
dashedLine(n);
}
//This method will print the dashed line for number greater than zer
private static void dashedLine(int n) {
if (n > 0) {
for (int i = 1; i <= n; i++) {
System.out.print("-");
}
System.out.println();
}
}
}
