Glossary Terms -
Electromagnetic Spectrum - is a range of different sized wavelengths and wave frequencies. where the wave is on this spectrum determines the type of energy that it is
Visible Light - it travels through the fog particles that reflect of it and create the light to see through the fog.
Infrared Radiation - Infrared cannot be seen by the human eye. infrared is emitted by all the objects that is sensed as heat, so as the heat increases the amount of infra red radiation.
Ultra-Violet Radiation - is needed by most humans to help the body obtain vitamin D, ( the suns radiation. ) this can also not be seen by the human eye
Electromagnetic Waves - refers to all the different sized waves of energy that travel around in our universe
Reflection - is when a light bounces off a surface of a substance. it allows you to see non luminous objects.
Refraction - refraction occurs when there is a change in the speed of light, it passes from one substance to a different substance. it results in changing the direction.
Concave - is having an outline that curves inwards so it has an interior of a circle or a sphere.
Convex - having a surface curved like the exterior of a circle or sphere.
Reverberation - a continuing effect of sound, like an echo
Sound Waves - a mixture between compressions and rarefactions
Rarefactions - Rarefactions are air particles that are further apart than usual particles
Compressions - Compressions are air particles that are closer together than usual particles
Amplitude - the height of the wave
Wave Length - the distance that is between two like parts of a wave
Wave of Energy -the energy that the wave moves from one point to another
Transverse Wave -is a particle that goes up and down but the wave goes left to right , the particle is moving perpendicular to the direction of the wave)
Compression Wave - ( another word for Longitudinal wave ) is a vibrating particle vibrates left and right, it then pushes other particles which push more particles, the particles move in the same direction the wave is moving
Frequency - is the number of complete vibrations that the wave had made in one second, it is also measuring in Hertz ( Hz )
Medium - is the material that moves through the particles which the waves go through
Radio Waves - an electromagnetic wave that has the frequency between 10^4 Hz as it is used for long distance communication
Transmitter - equipment that is used to transmit electromagnetic waves
AM - Amplitude Modulation
FM - Frequency Modulation
Wireless communication:Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor
Microwave: it is electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation.
Coaxial cables: A transmission line that consists of a tube of electrically conducting material surrounding a central conductor held in place by insulators and that is used to transmit telegraph, telephone, and television signals
Optical fiber: A thin glass fibre through which light can be transmitted
Satellite dishes: A bowl-shaped aerial with which signals are transmitted to or received from a communications satellite.
