Mechanical waves

Subject: Physics

Grade: Lower Secondary

Publisher: YDP

Resource types: Whiteboard presentation

Resource ID: g2131
Description:

At the end of this activity, students should be able to:
– explain how waves carry energy
– explain the concept of a mechanical wave, wavelength, frequency and amplitude
– calculate the wavelength (of a specific frequency) in a specific medium when the velocity of wave propagation in this medium is given
– describe the behaviour of a wave when it passes from one medium to another.
