Statement 1: A tuning fork of constant frequency sends sound waves in air. If temperature of the air increases, then the wavelength of sound wave in air decreases. Statement 2: Speed of sound in air increases with increases in temperature of airA. Statement-1 is true, Statement-2: is true, Statement-2 is a correct explanation for Statement-1.B. Statement-1 is true, Statement-2: is true, Statement-2 is NOT a correct explanation for Statement-1.C. Statement-1 is true but statement-2 is falseD. Statement-1 is false, Statement-2 is true |
