SCIENCE ON REFLECTION AND REFRACTION OF LIGHT Flashcards
IT IS ELECTROMAGNETIC RADIATION THAT HAS PROPERTIES OF WAVES AND PARTICLES.
LIGHT
LIGHT WAVES ALSO BOUNCE OFF FROM A REFLECTING SURFACE AND THIS PROPERTY IS CALLED.
REFLECTION OF LIGHT OR REFLECTION
TWO KINDS OF REFLECTION
SPECULAR REFLECTION
DIFFUSED REFLECTION
OCCURS WHEN THE REFLECTIVE SURFACE IS VERY SMOOTH SUCH AS A MIRROR OR A SURFACE OF CALM WATER.
SPECULAR REFLECTION
IS OBSERVED WHEN LIGHT HITS A ROUGH SURFACE RESULTING IN THE BOUNCING BACK OF LIGHT WAVES IN A DIFFERENT DIRECTION
DIFFUSED REFLECTION
A SMOOTH REFLECTING SURFACE THAT PRODUCES A SPECULAR REFLECTION OF RED RAYS MAY PRODUCE DIFFUSE REFLECTION WHEN INCIDENT UPON BY VIOLET RAYS
DIFFUSION
DISPERSAL OF REFLECTED LIGHT IS CALLED
DIFFUSION
IS THE TRANSFER OF ENERGY CARRIED BY THE LIGHT WAVES TO THE PARTICLES OF MATTER
ABSORPTION
IS THE REFLECTION OF LIGHT BY PARTICLES.
SCATTERING
IS STRICTLY OBSERVED WHEN THE REFLECTING SURFACE IS SMOOTH.
LAW OF REFLECTION OR LAW OF REFLECTION OF LIGHT
IN LAW OF REFLECTION OR LAW OF REFLECTION OF LIGHT
WHEN THE LIGHT IS EXITING FROM A MEDIUM, _____ _______ ________ CAN OCCUR IF THE ANGLE OF INCIDENCE IS GREATER THAN THE CRITICAL ANGLE.
TOTAL INTERNAL REFLECTION
THE 2 LAW OF REFLECTION OF LIGHT
A. THE ANGLE OF INCIDENCE IS EQUAL TO THE ANGLE OF REFLECTION
B. THE INCIDENT RAY, THE NORMAL TO THE MIRROR AT THE POINT OF INCIDENCE, AND THE REFLECTED RAY ALL LIE IN THE SAME PLANE.
IT IS THE BENDING OF LIGHT AS IT PASSES FROM ONE MEDIUM TO ANOTHER.
REFRACTION OF LIGHT
THE EFFECT ASSOCIATED WITH THE SEPARATION OF LIGHT INTO COLORS BY A PRISM
DISPERSION
NEWTON’S EXPERIMENT CONFIRMED THAT WHEN A LIGHT WAS MADE TO PASS THROUGH A PRISM, ITS COMPONENTS REFRACTED AT THE DIFFERENT ANGLES ON ACCOUNT OF THEIR DIFFERENT WAVELENGHTS.
DISPERSION
