Transverse wave particles travel___ to the direction of propagation
Perpendicularly
Directly
Diagonally
Parallel
Inwardly
Longitudinal wave particles travel___ to the direction of propagation.
Perpendicularly
Directly
Diagonally
Parallel
Inwardly
What is a transverse wave?
This is the kind of mechanical wave that involves the particles of the medium travelling perpendicularly to the direction of the wave’s propagation.
What is a longitudinal wave?
This is the kind of mechanical wave in which the particles of the medium travels parallel to the direction of the propagation of the wave.
Which of the following is not a wave characteristic?
Wavelength
Speed
Momentum
Frequency
Amplitude
If period is the reciprocal of frequency, this means that
T = 1÷f
T = 2 × f
T = f2
T = f÷2
T = √f
Lambda (λ) is the unit of measurement of which wave characteristic?
Speed
Phase
Frequency
Wavelength
Wavefront
The amplitude of a wave is defined as___
the ability of a wave to travel through a void
the distance between the origin and the medium
the distance between two adjacent crests or troughs along the wave
the time taken for the wave to complete one cycle
the maximum displacement a particle experiences from its equilibrium
Amplitude is the maximum displacement a particle experiences from its equilibrium
The frequency of a wave is measured in___
Centihertz (CHz)
Hertz (Hz)
Meters (m)
Time (T)
Grams (g)
Mention and explain any four (4) characteristics of waves.
-
Period of a wave is the time taken for the wave to complete one cycle. It is denoted by “T” and is measured in seconds. It is the reciprocal of the frequency. Thus, T = 1/f
-
Phase of a wave refers to any one point in a recurring series of motions of the particles constituting a displacement.
-
Speed of a wave refers to how quickly a wave propagates through its medium. It is influenced by the features of the medium and the wave itself.
-
Wavefront of a wave refers to any cross-section of the advancing wave in which all particles are in the same phase.
