Properties of Waves and Light

In this courses you will cover the topics related to the properties of waves, namely:

• Wave motion: e.g. vibrations in ropes, Springs
• Different types of wave: Transverse (water and light waves) and Longitudinal (sound waves) in terms of direction of oscillation
• The wave equation: Displacement-time and displacement – distance graphs of a wave. (Use the equation v = fl.)
• Use of waves in our life: radio, television, ultrasonic etc.

• Scientific terms: Propagation-transmission, reflection- and refraction of waves. Diffraction of waves using wide, narrow gaps, sharp edges.
• Two types of Interference of waves: such as Constructive and destructive

• The characteristics of sound waves: Loudness of sound and its amplitude
• Pitch of sound and its frequency
• Factors which influence the quality of sound: such as overtones or wave form of the note
• Production of sound using vibrating objects
• Sound wave essentials: rarefactions (stretches) and compressions (“Squashes”)
• Range of audible sound frequencies (20Hz to 20000Hz)
• Effects of sound waves traveling through air and a vacuum
• Speed of sound in air (approximately 330m/s)
• Respective speeds of sound in solids, liquids and gases
• The characteristics of sound waves: Loudness of sound and its amplitude
• Pitch of sound and its frequency
• Factors which influence the quality of sound: such as overtones or wave form of the note
