- 1What is the Electromagnetic System?The range of wavelengths or frequencies over which electromagnetic radiation extends.
- 2What is a Medium?The medium of a wave is any substance that carries the wave, or through which the wave travels.
- 3What is an Energy Wave?A wave can be described as energy that travels through a medium from one location to another.
- 4What is a Transverse Wave?Transverse wave are light waves and is a wave where the particles are moving perpendicular to the medium
Compression Waves - 5What are Compression Waves?Compression waves are sound waves, they are made up of particles.
- 6What is the Frequency of a Wave?The frequency of a wave is referred to how the particles of the medium vibrate when the wave is passed through a medium.
- 7What is a Wavelength?The wavelength is the distance between two like parts of the wave
- 8What is the Amplitude of a Wave?The amplitude is the height of the wave
- 9What is Visible Light?Visible light is defined as wavelengths that are most visible to the human eye
- 10What is Infrared Radiation?Infrared radiation are invisible to the human eye but can be felt in the form of heat.
- 11What is UV light radiation?UV light radiation is light that comes from the sun, but is invisible to the human eye, the wave lengths are shorter than visible light, UV = Ultraviolet
- 12What are Electromagnetic Waves?Electromagnetic waves contain an electric field and a magnetic field and carry energy. They travel at the speed of light.
- 13What is the Reflection of a Wave?Reflection of a light wave is where the light can bounce back from the material
- 14What is the Refraction of a Wave?Refraction of a light is where the light is bended
- 15What is the meaning of Concave?Having an outline or surface that curves inwards
- 16What is the meaning of Convex?Having an outline or surface that curves outwards
- 17What is a Compression Wave?A sound wave
- 18What are RarefactionsA rarefaction is a region in a longitudinal wave where the particles are furthest apart.
- 19What are Sound Waves?Sound waves are formed when sound is made and moves through the air and carries the sound to your ear
- 20What is the meaning of Reverberation?Reverberation is a reflection of light or sound waves, or a wide reaching impact of an action
- 21What are Radio Waves?An electromagnetic wave used in radio, television, or radar communication.
- 22What are TransmittersA set of equipment used to generate and transmit electromagnetic waves carrying messages or signals, especially those of radio or television.
- 23What are AM & FM Waves?AM & FM waves carries commercial radio signals
- 24What is Wireless Communication?Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor.
- 25What are Microwaves?Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes.
- 26What are Coaxial Cables?Coaxial cables are physical channels that carries the signals to the desired destination.
- 27What are Optical Fibres?Optical fibers are thin glass fibre through which light can be transmitted.
- 28What are Satellite Dishes?Satellite dishes are bowl-shaped aerial with which signals are transmitted to or received from a communications satellite.
