Answer» Correct Answer - A `{:(A - c,, "frequency " = ("Number of oscillations")/("Time taken")),(B - d,, "The loudness of sound depends upons the amplitude of vibrations."),(C - c,, "The angle of incidence is equal to the angle of reflection of the sound."),(D - a,, "Ultrasounds are used to detect flaws present inside a metal."),(E - b,, "Manjira, the ghatam, jal tarang are examples of Ghana vadya."):}` |
