Analysing Reflection of WavesFigure shows the reflection of sea waves by a retaining wall built near the beach. Reflection of waves is a phenomenon that occurs when all or a part of the waves return after they encounter an obstacle. The obstacle is know…

Analysing Electromagnetic WavesThe electromagnetic spectrum consists of a group of waves of similar nature. The members of the electromagnetic spectrum arranged in increasing frequencies (decreasing wavelengths) are radio waves, microwaves, infrared rays…

Analysing Diffraction of WavesFigure shows a scenery of a fishing village. It is noticed that when the waves passed through the narrow opening between the two concrete barriers, their shape changed. This observation can be explained by the diffraction of…

Analysing Refraction of WavesFigure shows a surfer approaching the beach. As the waves enter the shallow water near the beach, the wavelength of the waves decreases. Hence, the speed of the waves decreases as the water gets shallower. Refraction of waves…

Analysing Sound WavesSounds are mechanical waves. They are caused by vibrating objects. The string of a guitar, the skin of a drum and a tuning fork, all of these vibrate to produce sound. The vibrating cone of a loudspeaker in Figure produces sound. Its…

Analysing Interference of WavesFigure shows two drops of rain water falling on the surface of a pond, producing two sets of circular waves. When the two sets of waves overlap with each other, they will form an interference pattern. Interference of waves …
