Sound energy is basically:
The transfer of energy in a material medium due to the periodic motion of its particles is called:
Which is not the condition for hearing sound?
An instrument commonly used in laboratory to produce a sound of some particular frequency is :
The correct answer is C as Tuning fork is an instrument used to produce sound in fixed frequency in laboratories. A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs formed from a U-shaped bar of elastic metal .
The sound waves in a medium are characterised by the:
The sound waves which travel in the air are called:
When a sound wave travels in the air, the physical quantity which is transferred from one place to the other is:
In case of longitudinal waves, the particles of medium vibrate:
In case of transverse waves the particles of a medium vibrate:
A longitudinal waves consists of:
A transverse wave consists of:
The longitudinal waves can propagate only in :
Which of the following metal/s is/are not ductile?
A part of the longitudinal wave in which particles of medium are closer than the normal particles is called:
In the compression region of the medium in case of longitudinal wave:
A part of longitudinal wave in which particles of medium are farther away than the normal particles is called:
In case of a longitudinal wave, in the region of rarefaction :
In the region of compression or rarefaction, in a longitudinal wave the physical quantity which does not change is:
A slinky can produce in laboratory :
A slinky can easily demonstrate the two basic types of waves, longitudinal & transverse. In a Longitudinal wave the particles move parallel to the direction the wave is moving. In a transverse wave the particles move at right angles to the direction of wave travel.
In case of transverse wave :
The highest part of the wave is called the crest. The lowest part is called the trough. The wave height is the overall vertical change in height between the crest and the trough and distance between two successive crests (or troughs) is the length of the wave or wavelength.
In case of transverse wave:
The wavelength is the linear distance between the:
The distance between two successive compression and distance between a compression and the adjoining rarefaction is called wavelength.
In case of transverse wave the wavelength is the linear distance between :
The change in density/pressure of a medium from maximum value to minimum value and again to maximum value, due to the propagation of a longitudinal wave is called complete:
The number of oscillations passing through a point in unit time is called:
