1) The electromagnetic spectrum is a representation of all the electromagnetic waves that exist around us. Both visible or invisible, they can all be detected directly or inferred.
2) From high frequency to low frequency. Gamma Rays, X-Rays, Ultraviolet, Visible, Infrared, Radio.
3) Only waves that have wavelengths between 400 nm and 700 nm are visible to humans. All high energy waves can damage cells (Gamma, X, Ultraviolet).
4) Refraction is the bending of light at angles depending on the refractory index of the medium, reflection is when light leaves an object at the same angle it entered and object. Absorption is when the energy of a wave is transferred to the electrons of an object the waves are interacting with.
5) Sound waves are shock waves caused by a disturbance in the air/water/rock around us. Sound waves have a greater capacity to perform work in relation to light waves.
6) Frequency is measured in Hertz.
Amplitude is measured using a floating variable depending on the wave.
Wavelength is measured utilizing a SI unit depending on the rough displacement of the wave. Visible light is measured in nanometers, Infrared is measured in micrometers and radio waves are sometimes measured in kilometers
7) The displacement from one end on the wave to a corresponding end after following amplitude.
8) Convection, is the relay of energy via liquid or gaseous mediums. (e.g. water)
Conduction, is the relay of energy via solid matter (e.g. metal rod).
Radiation, is the relay of energy independent of conductive mediums (e.g. through space).
9) The law of conservation of energy or the first law of thermodynamics states that energy cannot be created or destroyed only converted into another form.
B.Sc Zoology, basic physics is a requirement.
