General Properties Of Waves Continued
Muhtasari
Drop a stone in a pond and circular ripples spread out; they bounce off a wall, bend where the water is shallow, and spread through a gap. Those same three behaviours, reflection, refraction and diffraction, are shown by every wave, from water ripples to light and sound.
In this lesson you will distinguish longitudinal from transverse waves, describe how waves reflect, refract and diffract, and explain how a ripple tank demonstrates each one. You will also learn how the size of a gap and the wavelength control how much a wave spreads out.
Malengo
- Know that for a longitudinal wave, the direction of vibration is parallel to the direction of propagation and understand that sound waves and seismic P-waves (primary) can be modelled as longitudinal
- Describe how waves can undergo: (a) reflection at a plane surface (b) refraction due to a change of speed (c) diffraction through a narrow gap
- Describe the use of a ripple tank to show: (a) reflection at a plane surface (b) refraction due to a change in speed caused by a change in depth (c) diffraction due to a gap (d) diffraction due to an edge
- [Supplement] Describe how wavelength and gap size affects diffraction through a gap
- [Supplement] Describe how wavelength affects diffraction at an edge
