optics Flashcards
what is the height or depth of a wave?
amplitude
how do we measure frequency
in Hurtz (Hz)
wavelength is…
the distance of 1 wave cycle (resting point, to crest, to trough, then back to resting point)
what is the 5 parts of a wave?
crest, trough, amplitude, resting point and wavelength
the wavelength th of a wave decreases as ___________ increases
frequency
true or false: waves move matter forward
FALSE - waves move matter up + down
frequency =
cycles over seconds
the larger the amplitude the….
…higher the frequency
the smaller the frequency the…
larger the wavelength
electromagnetic spectrum is
the entire range of radiant energy
light energy is a form of
radiant energy
what is the order of waves from least frequency to most
radio waves, microwaves, infrared waves, visible spectrum, ultraviolet rays, X - rays, and gamma rays
our eyes detect how many rays of light?
7
our light starts at the
sun
the primary colours of light are
red green and blue
