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 waves8. Grating element is equal tocosθnλ/sinθsinθnλ9. A taunt wire is clamped at two points 1.0m apart. It plucked near one end.

Splitting of white light in to constituent colors is calledrefractiondiffractionreflectiondispersion11. A double-slit interference of green-coloured light was set up as shown and interference fringes are formed on the screen.Which change would increase the distance between adjacent fringes?Reduce the width of each slit.Use orange-coloured light.Use a double-slit where the slits are further apart.Move the double-slit closer to the screen.12. Constructive interference happens when two waves arein frontzero amplitudein phaseout of phase13. If two sound waves having a phase difference of 60°, then they will have a path difference of _____ʎ/3ʎ/6ʎ3ʎ14. The diagram shows a standing wave on a string. The standing wave has three nodes N1, N2 and N3.Which statement is correct?All points on the string vibrate with the same amplitude.Points equidistant from N2 vibrate with the same frequency and in phase.Points equidistant from N2 vibrate with the same frequency and the same amplitude.All points on the string vibrate in phase.15. In young double slit experiment, the wavelength of incident beams should beoppositedifferentsamezero16. For listening radio in cars, external radio aerials are used becauseradio waves have shorter wavelengthradio waves have longer wavelengthradio waves cannot pass through windowradio waves require a medium to propagate17. 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?Increasing the frequency emitted by the loudspeaker.Moving the loudspeaker closer to the wall.Moving the loudspeaker towards L.Increasing the loudness of the sound emitted by the loudspeaker.18. With diffraction grating, the angles arezerogreaterclose to zerosmall19. A suspension bridge is to be built across a valley where it is known that the wind can gust at 5 second interval. It is estimated that speed of transverse waves along the span of the bridge would be 400 m/s. The danger of resonant motion in the bridge at its fundamental frequency would be the greatest if the span had a length of2000 m1000 m400 m80 m20. Wavelength of an incident light when it is incident normally on a diffraction grating having 3000 lines per centimeter angular separation is 10° is650 nm580 nm600 nm500 nm21. Two transverse waves overlap. Crests overlap with troughs. Troughs overlap with crests. The waves areIn-synchronicityOut-of-phaseOut-of-synchronicityIn-phase22. For a wave propagating in a medium, identify the property that is independent of the others.WavelengthsVelocityFrequencyAll these depend on each other23. Two waves with phase difference 180° have resultant of amplitudedoubles the single wavesame as the single waveonezero24. A speaker producing sound of frequency 2500 Hz is placed at the open end of a closed pipe containing a gas.As the piston is moved along the pipe, a series of 6 loud sounds was heard. The first loud sound was observed when the piston was 4.0 cm away from the open end, and the sixth loud sound was observed when the piston was 37 cm away from the open end. What is the speed of sound in the gas?330 m/s270 m/s370 m/s400 m/s25. The plane wave is described by the equationy=3cos(x/4-10t-π/2),Where c is in meters and t in seconds. The maximum velocity of the particles of the medium due to this is?40m/s3π/2 m/s30m/s3/4 m/s26 out of 25Time is Up!
