Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
A sound wave of wavelength 40 cm travels in air. If the difference between the maximum and minimum pressures at a given point is 1.0 x 10–3 N/m2, find the amplitude of vibration of the particles of the medium. The bulk modulus of air is 1.4 x 105 N/m2. A sound wave of wavelength 40 cm travels in air.
