solve this and explain---A wave on the surface of a ripple tank moves from the source at the rear of the tank to the front. The graph shows the variation with distance x of the displacement y of the surface of the water.
The solid line shows displacement at t = 0 and the dashed line shows the displacement at t = 0.154 s.
Chart/Diagram Description:
Type: Line graph showing the displacement (y) of a wave as a function of distance (x).
X-axis: Labeled "x / cm", scale from 0 to 6.0 with major ticks at 1.0 cm intervals.
Y-axis: Labeled "y / mm", scale from -4 to 4 with major ticks at 1 mm intervals.
Data Series:
- Solid line: Represents displacement at t = 0. Shows a wave starting at y=0 at x=0, peaking at approximately y=4 mm at x=1.0 cm, crossing the axis at x=2.0 cm, reaching a trough at approximately y=-4 mm at x=3.0 cm, crossing the axis at x=4.0 cm, peaking at approximately y=4 mm at x=5.0 cm, and crossing the axis at x=6.0 cm. Appears to be a sine wave with amplitude 4 mm and wavelength 4 cm.
- Dashed line: Represents displacement at t = 0.154 s. Shows a wave shifted horizontally to the right relative to the solid line. It crosses the axis around x=0.5 cm, peaks around x=1.5 cm, crosses the axis around x=2.5 cm, reaches a trough around x=3.5 cm, crosses the axis around x=4.5 cm, and peaks around x=5.5 cm. The shift is approximately 1.0 cm to the right.
Grid: A grid is overlaid on the graph to aid in reading values.

Waves are classified into two main types based on how particles move relative to the wave's direction. In transverse waves, particles oscillate perpendicular to the wave direction, like waves on a string. In longitudinal waves, particles oscillate parallel to the wave direction, like sound waves in air.
Transverse waves include light waves, radio waves, waves on a string, and surface water waves. The key characteristic is that particles move perpendicular to the wave direction. Here we see a wave traveling along a string where particles oscillate up and down while the wave moves horizontally.
Longitudinal waves include sound waves, ultrasound, seismic P-waves, and compression waves in springs. In these waves, particles oscillate parallel to the wave direction, creating regions of compression where particles are close together and rarefactions where they are spread apart.
The key differences between transverse and longitudinal waves are clear. In transverse waves, particles oscillate perpendicular to the wave direction and can be polarized. In longitudinal waves, particles oscillate parallel to the wave direction and cannot be polarized. Transverse waves can travel through vacuum, while longitudinal waves require a medium.
To summarize what we have learned: Wave classification depends on the direction of particle motion relative to wave propagation. Transverse waves have particles moving perpendicular to the wave direction, while longitudinal waves have particles moving parallel to it. Understanding these fundamental differences helps us identify and analyze wave behavior in physics and engineering applications.
