If two sound waves having a phase difference of 60°, then they will have a path difference of _____ʎ/3ʎ/6ʎ3ʎ7. Two waves with phase difference 180° have resultant of amplitudedoubles the single wavesame as the single waveonezero8. Constructive interference happens when two waves arein frontzero amplitudein phaseout of phase9. A transverse wave passes through a string with the equationy=10sinπ(0.02x-2t)Where x is in metres and t in seconds. What is the maximum velocity of the particles in wave motion?78m/s100m/s63m/s121m/s10. Splitting of white light in to constituent colors is calleddispersionrefractiondiffractionreflection11. Which of the following is always true for a stationary wave?The particles in the wave oscillate perpendicularly to the direction of wave travelNo energy is transferred from one end of the wave to the other.All particles have the same amplitude.All particles vibrate in simple harmonic motion with the same frequency as the wave12. A loudspeaker at position S emits sound of a single frequency. The sound travels to Leo who is at position L, both through a straight path and after reflection from a wall as shown.As Leo walks directly towards the wall, the sound alternates between loud and soft. Which of the following changes would result in an increase in the distance between loud and soft sounds?Moving the loudspeaker closer to the wall.Moving the loudspeaker towards L.Increasing the loudness of the sound emitted by the loudspeaker.Increasing the frequency emitted by the loudspeaker.13. Microwaves have wavelength of about20 cm30 cm40 cm10 cm14. Two transverse waves overlap. Crests overlap with troughs. Troughs overlap with crests. The waves areOut-of-synchronicityIn-phaseIn-synchronicityOut-of-phase15. A wire is stretched over two supports, Q and R, a distance 4x apart. Three light pieces of paper rest on the wireWhen the wire is made to vibrate at one particular frequency, the middle piece of paper stays on, but the others fall off the wire.The wavelength of the vibration produced on the wire?4x3x2x8x16. The waves, in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion, is known as ______Magnetic wavesLongitudinal wavesPropagated wavesTransverse waves17.
