Exploring Wave Properties: Reflection, Refraction, Diffraction, and Polarisation

The video tutorial explores various wave properties using a ripple tank and a mobile app. It covers the concepts of reflection, refraction, diffraction, and polarization, explaining how these phenomena occur in different types of waves, such as electromagnetic and mechanical waves. The tutorial also demonstrates how to model these properties using digital tools, providing practical examples and explanations for each wave behavior.

What happens to a wavefront when it hits a different medium at an angle?

• It stops

• It bends

Why can sound waves diffract through an opening but light waves cannot?

• Because sound waves are mechanical

• Because light waves are transverse

• Because the gap is too small for light

• Because sound waves are longer

• Transverse waves

• Mechanical waves

• Longitudinal waves

• Electromagnetic waves
