1. What does the relation v = fbb describe for a travelling wave?
2. In a fixed medium where wave speed stays constant, what happens to the wavelength if the frequency increases?
3. What remains unchanged when a plane wave reflects from a boundary?
Travelling wave — definition?
A disturbance propagating energy without matter transport.
Wave speed relation?
v = f λ, relates speed, frequency, wavelength.
Transverse wave — displacement?
Displacement is perpendicular to propagation direction.
Longitudinal wave — displacement?
Displacement is parallel to propagation direction.
Wavefronts — purpose?
Visualize wave propagation and phase.
Reflection — wave property?
Wave bounces, angle of incidence equals angle of reflection.
