Question
1. A single disturbance that moves from point to point through a medium is called a_. a. period b. periodic wave c. wavelength d. pulse 2. If the particles of the medium are vibrating to and fro in the same direction of energy transport, then the wave wave. a. longitudinal b. sound c. standing d. transverse 3. When the particles of a medium are vibrating at right angles to the direction of energy transport, then the wave is a wave a. longitudinal b. sound c. standing d. transverse 4. A transverse wave is traveling through a medium. See diagram below. The particles of the medium are vibrating a. parallel to the line joining AD b. along the line joining CI c. perpendicular to the line joining AD d. at various angles to the line Cl. e. along the curve CAEJGBI.Explanation / Answer
1(d) SINGLE disturbance can be called as pulse
2(a) If disturbance(vibration) is in the same direction as propogation, they are termed as longitudinal waves. Eg: sound waves: the disturbance is caused in pressure along the direction of motion of sound.
3(d) if vibration is in perpendicular to the propagation direction, waves are termed as transverse.
4(a) since it is given to be a transverse wave, the vibration direction is perpendicular to propogation and so along the direction of AD.
