Introduction to Waves - SS3 Physics Past Questions and Answers - page 1

A wave can be described as a periodic or non-periodic oscillation or vibration that travels through a medium, such as air, water, or even a vacuum (empty space).

Waves are fundamental to several fields of science and theology as they help us to 

• Understand natural phenomena such as earthquakes, tsunamis, weather patterns, and the behaviour of light and sound

• Advancement in technology; many modern-day technologies such as telecommunications, radio, television broadcasting, and medical imaging technology (ultrasound), are all made possible based on the theoretical understanding of waves.

• Material research is made possible by the study of waves as they help researchers and scientists obtain information on elasticity, viscosity and other physical properties.

• Progress in fundamental physics is made possible by the study of waves in areas such as quantum mechanics and the study of particles and their interactions.
