what is quantum theory? it is a theory that describes how light and matter exists in small and tiny particles which have a wave like property
light is composed of particles called? Photons
Does light behave as a wave? Light DOES behave as a wave
who proposed the idea that light behaves as a wave? Christiaan Huygens, a Dutch physicist
Give an example of wave behavior? diffraction, interference
what is wave diffraction? diffraction is the spreading out of plane waves as they pass through a hole
when does constructive interference occur? constructive interference occurs when wave crests meet
when does destructive interference occur? destructive interference occurs when wave crests and troughs meet
who proposed the idea that light is an electromagnetic wave that travels through space at the seed of light? Clerk Maxwell
The frequency of light is related to _______ the wavelength of the light
which formula is used to calculate the frequency of a wave? frequency (v) = speed of light (C) / wavelength
what is the frequency of a wave given that the wavelength of a light blue is 436nm? ( 3.00 x 10^8 m/s ) x ( 436nm ) x ( 10^9nm/m) = 6.88 x 10^14 s^-1
what is the region of visible light? the region of visible light is between 400 and 750 nm
Can the human eye see light between 400 and 750 nm? Yes, this is the visible region of light
Light that has all the frequencies in the visible region will show as ______ light white light
what are some regions of the electromagnetic spectrum? radio waves, infra Red region, Ultra Violet region, X ray
