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 known as a reflector. A ripple tank kit is a very useful apparatus for studying waves in the laboratory. Figure shows … [Read more...] about Analysing Reflection of Waves

Analysing Electromagnetic Waves
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, visible light, ultraviolet rays, X-rays and gamma rays. Electromagnetic waves are joint electric and magnetic … [Read more...] about Analysing Electromagnetic Waves
Analysing Diffraction of Waves
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 waves.Diffraction of waves is a phenomenon that refers to the spreading out of waves when they move through a gap … [Read more...] about Analysing Diffraction of Waves
Analysing Refraction of Waves
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 is a phenomenon that occurs when there is a change of direction in the propagation of waves travelling from one … [Read more...] about Analysing Refraction of Waves
Analysing Sound 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 vibrating diaphragm is continually compressing and stretching the air next to it. This makes a series of … [Read more...] about Analysing Sound Waves
