Question

E 2yBooks On a piano, each key has a frequency, and each subsequent key (black or white) s a known amount higher For example. The A key above the middle C key has a frequency of 440 Hz Each subsequent key (black or white) h keys from that A key, and r is 2112) Given an initial frequency, output that frequency and the next 4 higher key tequencies. as a frequency of 440 rft where n is the number of Ex If the input is 440, the output is 440 466.1637615180899 493.9833012561 1241 523.2511306011974 534.3652619537443 Note Include one statement to compute r - 2(1o120 using the paw function, then use t in the formule oYoul have four statements using that formula different only in the value for n) ATY31: LAB Musical note frequencies texpressions/assignments D/ 10 LabProgram java Lnad default template, spert 1. 3 Pub33C class LabProgran Java.ut1 1.

Explanation / Answer

import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner in = new Scanner(System.in); int f = in.nextInt(); double r = Math.pow(2, 1.0/12); System.out.println(f + " " + f*Math.pow(r, 1) + " " + f*Math.pow(r, 2) + " " + f*Math.pow(r, 3) + " " + f*Math.pow(r, 4)); } }
