Sound Waves Short Question With Answer: General Science Cadet College Test
[toggle title=”Q.No.01: Define wave?” state=”close”] Ans: Wave is a disturbance that transfers energy from one point to the other. [/toggle]
[toggle title=”Q.No.02: What is Medium?” state=”close”] Ans: Many waves require some material to travel through. This material thing is called a medium. [/toggle]
[toggle title=”Q.No.03: Define Transverse waves?” state=”close”] Ans: A wave in which particles of the medium move perpendicularly to the path of the wave is called transverse wave.
e.g., water waves. [/toggle]
[toggle title=”Q.No.04: What is the difference b/w crest & trough?” state=”close”] Ans: (1) The highest point of a transverse wave is called a crest.
(2) Lowest point between two crests is called trough. [/toggle]
[toggle title=”Q.No.05: Define longitudinal waves.” state=”close”] Ans: A wave in which particles of medium move back and forth, parallel to the path of wave is called longitudinal wave. [/toggle]
[toggle title=”Q.No.06: What do you know about compression?” state=”close”] Ans: The parts of a longitudinal wave where particles of the medium are compressed together are called compression. [/toggle]
[toggle title=”Q.No.07: How will you define a rarefaction?” state=”close”] Ans: The parts of a longitudinal wave where particles of the medium are spread out are called rarefaction. [/toggle]
[toggle title=”Q.No.08: How sound waves reach our ears?” state=”close”] Ans: Sound waves from a vibrating body produce longitudinal waves in the air. These waves reach our eardrum. [/toggle]
[toggle title=”Q.No.09: Define electrical energy?” state=”close”] Ans: The energy of moving electric charges within a circuit is called electrical energy. [/toggle]
[toggle title=”Q.No.10: Define wavelength?” state=”close”] Ans: A wavelength is the shortest distance between two adjacent crests or troughs of a transverse wave. [/toggle]
[toggle title=”Q.No.11: How is the wavelength of longitudinal waves measured?” state=”close”] Ans: For longitudinal waves, it is the distance between two adjacent compressions or rarefactions. [/toggle]
[toggle title=”Q.No.12: Define Amplitude?” state=”close”] Ans: Amplitude of a wave is the maximum distance of a vibrating wave from its rest position. [/toggle]
[toggle title=”Q.No.13: What is wave frequency?” state=”close”] Ans: Wave frequency is the number of waves that pass a point in one second. It is measured in hertz (Hz). [/toggle]
[toggle title=”Q.No.14: What is wave speed?” state=”close”] Ans: Wave speed is the distance a wave travels per unit of time. [/toggle]
[toggle title=”Q.No.15: What is the period of a wave?” state=”close”] Ans: The period is the time taken for one complete wave to pass a point. [/toggle]
