Optics 3 Point Approach Flashcards
spectrum
the range of colours that result from the separation of white light
wavelength
distance from one wave crest to the next
opaque
material that prevents visible light from penetrating it
composed of the most compressed wavelengths and has highest frequency
microwaves
reflection
process wherein light hits a surface and is sent back from the surface
distance between the crest and the resting position of a wavelength
distance between the trough and the resting position of a wavelength
amplitude
the changing of direction or bending of light when travelling from one medium to another medium, having different density
refraction
form of energy that can be detected with the eyes
visible light
transparent
material that allows light to pass through with no change in direction of rays
objects can be clearly seen through material
energy in the form of waves
repetitive movement (not of particles) of electric and magnetic energy through space
electromagnetic spectrum/radiation
imaginary line perpendicular to a surface
normal
incident ray
ray that strikes a reflecting or refracting surface
reflected ray
ray leaving a reflecting surface after an incoming ray has struck the surface
curved mirror for which centre is behind outer edges; mirrored surface curved inward
shaped like inside of a bowl
concave mirror
