ANSWERS UPDATED .Buy Quality Materials!
Define wavelength
distance from crest to crest or trough to trough
What is the unit symbol of wavelength
m
Define frequency
The number of crests of a wave passing a stationary point of reference per unit of time
Define Amplitude
Height of the crest or depth of the trough
Define refraction
The bending of light waves when passing between media of different densities
Define Interference
The interaction of waves in which their amplitudes either reinforce (constructive) or
cancel (destructive)
How is frequency and wavelength related
( inversely related ) meaning that as the frequency of a wave increases, its wavelength
decreases, and vice versa
Define Diffraction
The bending of light waves as they pass around the edge of an object or through narrow
openings
What characteristics does light have
Particle characteristics, Its energy is quantized
What is light energy proportional and inversely proportional to?
Proportional to frequency and inversely proportional to wavelength
Define Quantam
The smallest discrete quantity of a particular form of energy
Define Photon
Quantum of electromagnetic radiation
