<p>A. Amplitudo gelombang</p><p>&nbsp; &nbsp; &nbsp;Amplitudo adalah simpangan terjauh dari titik kesetimbangan</p><p>&nbsp; &nbsp; &nbsp;A = 9/2 = 4,5 cm</p><p>&nbsp; &nbsp; &nbsp;Amplitudonya adalah 4,5 cm</p><p>&nbsp;</p><p>B. Periode Gelombang (T)</p><p>&nbsp; &nbsp; &nbsp;n = 1,75 gelombang</p><p>&nbsp; &nbsp; &nbsp;t = 28 sekon</p><p>&nbsp; &nbsp; &nbsp;T = t/n</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 28/1,75</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 16 sekon</p><p>&nbsp;</p><p>C. Frekuensi Gelombang (f)</p><p>&nbsp; &nbsp; &nbsp;f = 1/T = 1/16 Hz = 0,0625 Hz</p><p>&nbsp; &nbsp; &nbsp;atau</p><p>&nbsp; &nbsp; &nbsp;f = n/t</p><p>&nbsp; &nbsp; &nbsp; &nbsp; = 1,75/28</p><p>&nbsp; &nbsp; &nbsp; &nbsp; = 0,0625 Hz</p><p>&nbsp;</p><p>D. Panjang Gelombang (𝞴)</p><p>&nbsp; &nbsp; &nbsp;1,75𝞴 = 56</p><p>&nbsp; &nbsp; &nbsp;𝞴 = 56/1,75</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = 32 cm</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; = 0,32 m</p><p>&nbsp;</p><p>E. Cepat rambat gelombang (V)</p><p>&nbsp; &nbsp; &nbsp;V = 𝞴 x f</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 32 x 0,0625</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 2 cm/s</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 0,02 m/s</p>
