Hint: The points of a transverse wave oscillate along the perpendicular path which shows the direction of the wave motion. This wave can be represented through a sine or cosine curve.
The amplitude of the wave is the highest displacement of the wave from its initial position and the wavelength can be measured from the length of the two consecutive highest picks of that wave.
Complete step by step answer:
• The diagram is showing that a wave is moving towards the horizontal direction i.e and each particle of the wave is moving towards the vertical direction i.e . Hence the motion of the wave and the motion of the particles is perpendicular to each other. So it is a transverse wave. Since the wave starts from the main point or the state, it describes a Sine wave.
• In the diagram is the amplitude. The amplitude of a wave can be defined as the highest displacement of the wave from its initial position.
• In the diagram is the wavelength of the wave. Wavelength is the length of a complete wave or we can say the distance between two consecutive same phased particles on the wave, is called the wavelength.
• Generally, we can also include that the length of the two consecutive highest picks of that wave is called the wavelength. Hence here in the diagram, the mentioned line is the wavelength as it is showing the distance between two consecutive
Note: The transverse wave can be represented by sine or cosine function as harmonic function. So we may write the equation of motion of a wave, and
Where, is the position of a particle on the wave at time , is the angular frequency and, is the amplitude.
Also the equation can be represented, and
is the displacement and is the velocity of the wave.
