Answer
An example of a transverse wave is light waves. These waves oscillate perpendicular to the direction of the wave's travel.

Answer
An example of a longitudinal wave is a sound wave. In these waves, the oscillations occur parallel to the direction of wave propagation.

Answer
To calculate the speed of the wave, we use the equation:
ext{wave speed} = rac{ ext{distance}}{ ext{time}}
Given that the distance travelled is 26,400 m and the time taken is 2 minutes (which is 120 seconds), we can substitute these values into the equation:
