LIGHT
- SPEED OF LIGHT IS 300,000,000 m/s
- LIGHT TRAVELS IN STRAIGHT LINES
- LIGHT CHANGES DIRECTION
WHEN THERE IS A CHANGE
OF MATERIAL
- YOU CAN SEE LUMINOUS
OBJECTS AS THEY ARE A
SOURCE OF LIGHT
- YOU CAN SEE
NON-LUMINOUS OBJECTS AS
THEY ARE REFLECTING LIGHT
FROM LUMINOUS OBJECTS
- A SHADOW IS AN AREA WHERE LESS LIGHT IS
REACHED COMPARED TO AREAS WHERE LIGHT
CAN REACH WITHOUT BEING DISTURBED
- SHADOWS IS FORMED WHEN LIGHT CANNOT PASS
THROUGH AN OBJECT AS IT IS OPAQUE AND LIGHT
TRAVELS IN STRAIGHT LINES
- IT TAKES ROUGHLY 8 MINUTES FOR
LIGHT TO REACH FROM THE SUN
TO THE MOON
- LIGHT TRAVELS FASTER THAN SOUND
- THE LAW OF REFLECTION IS THE ANGLE OF INCIDENCE
= THE ANGLE OF REFLECTION
- REFLECTION IS THE CHANGE IN
DIRECTION OF A LIGHTWAVE
- ALL LIGHT WAVES APPLY TO THE LAW OF REFLECTION
- CONCAVE MIRRORS ARE USED FOR FOCUSING LIGHT
- CONVEX MIRRORS ARE USED FOR
SPREADING OUT LIGHT
- TIR OCCURS WHEN A WAVE IS
REFLECTED FROM AN INSIDE ANGLE
- THE ONLY TIME TIR OCCURS IS
WHEN THE CRITICAL ANGLE IS MET
- WE CAN'T SEE IMAGES REFLECTED IN A SURFACE WHICH IS ROUGH BECAUSE
LIGHT GETS SCATTERED WHEN IT CAN'T TRAVEL IN STRAIGHT LINES AND THE
LIGHTWAVES WILL SHOOT RANDOMLY THEREFORE CANNOT PRODUCE A FULL
IMAGE
- TRANSPARENT IS A MATERIAL THAT ALLOWS LIGHT
TO TRAVEL THROUGH IN STRAIGHT LINES
FORMING A CLEAR IMAGES
- TRANSLUCENT IS A MATERIAL THAT WILL LET SOME LIGHT THROUGH HOWEVER
SLIGHTLY ROUGH SO LIGHT SCATTERS AS IT ENTERS SO IT DOESN'T SHOW A CLEAR
IMAGE
- OPAQUE IS A MATERIAL WHERE NO LIGHT CAN PASS THROUGH
- THE LAW OF REFRACTION IS THAT THE ANGLE OF INCIDENCE > ANGLE OF
REFRACTION
- REFRACTIVE INDEX REFERS TO HOW MUCH LIGHT IS
REFRACTED WHEN PASSING THROUGH A RANGE OF
MATERIALS.
- REFRACTION IS WHEN AN OBJECT BENDS A RAY OF
LIGHT BY CHANGING SPEED AND DIRECTION
