Analysing Electromagnetic Waves

1. Electromagnetic waves consist of vibration of magnetic field and electric field which are perpendicular to each other. 2. Therefore, Electromagnetic waves are transverse waves. 3. The velocity...

Electromagnetic Spectrum

When you watch television, listen to the radio or cook something in a microwave oven , you are actually apply the properties of electromagnetic waves. Do you know what is an electromagnetic wave? Electromagnetic waves are propagating waves that travel in space with both electric and magnetic components. These components oscillate at right angles to each other and to the direction...

Analysing Sound Waves

1. Sounds are mechanical waves. They are caused by vibrating objects. Hence, all vibrating objects produce sound. As an example: The strings of a guitar, the skin of a drum and a tuning fork vibrate...

Speed of Sound, Loudness and Amplitude of Sound

Speed of Sound 1. The speed of sound,v, in a medium can be defined as v = fλ, where λ is the wavelength and f is the frequency. The SI units of v is ms-1, f is Hz and λ is  m (metre). 2....

Analysing Diffraction of Waves

1. Diffraction of waves is a phenomenon in which waves spread out as they pass through an aperture or round a small obstacle. 2. The effect of diffraction is obvious only if a) the size of the...

Analysing Refraction of Waves

Any type of wave can be refracted, refracted is a change in direction. Refraction occurs when the speed of a wave changes, as it moves from one medium to another. Refraction of Plane Water Waves 1....
