Waves can be classified as either transverse or longitudinal depending on the direction of their oscillations relative to the direction of energy transfer.
Complete the table below by writing either transverse or longitudinal next to each description.
DescriptionType of waveThe oscillations are perpendicular to the direction of energy transfer.The oscillations are parallel to the direction of energy transfer.An electromagnetic wave (such as a radio wave) is an example of this type of wave.An ultrasound scan wave is an example of this type of wave. \begin{array}{|l|l|} \hline \textbf{Description} & \textbf{Type of wave} \\ \hline \text{The oscillations are perpendicular to the direction of energy transfer.} & \\ \hline \text{The oscillations are parallel to the direction of energy transfer.} & \\ \hline \text{An electromagnetic wave (such as a radio wave) is an example of this type of wave.} & \\ \hline \text{An ultrasound scan wave is an example of this type of wave.} & \\ \hline \end{array} DescriptionThe oscillations are perpendicular to the direction of energy transfer.The oscillations are parallel to the direction of energy transfer.An electromagnetic wave (such as a radio wave) is an example of this type of wave.An ultrasound scan wave is an example of this type of wave.Type of wave237 exam-style questions on CIE IGCSE Physics General properties of waves, covering General properties of waves.
