A sound source is moving towards stationary listener with 1/10th of the speed of sound. The ration of apparent of real frequency is 11/10 [9/10]² 10/9[11/10]² Question 1 of 13Question 2 of 13 2. Which one of the following properties is not exhibited by the longitudinal waves? Diffraction Reflection Interference Polarization Question 2 of 13Question 3 of 13 3. Which one of the following could be the frequency of ultraviolet radiation? 1.0 x 10¹²Hz1.0 x 10¹⁵Hz1.0 x 10⁶Hz 1.0 x 10⁹Hz Question 3 of 13Question 4 of 13 4. Which of the following changes at an antinode in a stationary wave? Pressure only Neither density nor pressure Both pressure and density Density only Question 4 of 13Question 5 of 13 5. A water wave move in two dimensions from the source point and at a far distance the curvature of the wave front becomes plane. As the wave proceeds the energy carried by the wave: Decreases Remains constant It needs some more information Increases Question 5 of 13Question 6 of 13 6. There is no net transfer of energy by particles of medium in. Stationary wave Transverse wave Longitudinal wave Progressive wave Question 6 of 13Question 7 of 13 7. When a transverse wave is reflected from the boundary of a denser to a rarer medium, it under goes a phase change of: π/2 π 0 2πQuestion 7 of 13Question 8 of 13 8. When a wave goes from one medium to another medium, which one of the following characteristics of the wave remains constant Wave length Velocity Phase Frequency Question 8 of 13Question 9 of 13 9. Which one of the following factors has no effect on the speed of sound in gas? Humidity Temperature Density Pressure Question 9 of 13Question 10 of 13 10. When sound waves travel from air to water which of these remain constant? Velocity Frequency All the above Wavelength Question 10 of 13Question 11 of 13 11. If the tension in the string is doubled and its mass per unit length is reduced to half. Then the speed of transverse wave on it is Doubled One fourthHalved Constant Question 11 of 13Question 12 of 13 12. When a stationary wave is formed then its frequency is: Same as that of the individual waves That of the individual waves Twice that of the individual waves Half that of the individual waves Question 12 of 13Question 13 of 13 13. A sounding source and a listener are both at rest relative to each other. If wind blows from the listener towards the source, then which one of the following of sound will change? Both Frequency and Speed Speed Frequency Wavelength Question 13 of 13 Loading...
