MODULE 4.3 LIGHT

THE SUN IS A NATURAL SOURCE OF LIGHT AND SHADOW FORMS WHEN ITS LIGHT IS BLOCKED

LIGHT IS A FORM OF ENERGY CALLED ELECTROMAGNETICS RADITION.

provide with light or lighting; illuminate.

LIGHT ALSO TRAVELS THROUGH SPACE FROM THE SUN TO EARTH, LIGHTING UP AND OUT DAY.

Light travels as a wave.

(300,000 KM)

(1,000,000 KM)

(6,000 KM)

AN OBJECT THAT RELEASES OR EMIT LIGHT.

brilliant intellectually; enlightened or enlightening, as a writer or a writer's works:

THE BOUNCING OF LIGHT OFF SOMETHING.

a fixing of the thoughts on something; careful consideration.

an image; representation; counterpart.

reflection such that the angle of reflection of the light is equal to the angle of incidence and on the opposite side of the normal to the point of incidence

REGULAR REFLECTION OCCURS FROM VERY SMOOTH SURFACES AND FORMS CLEAR, SHARP IMAGES.

Specular reflection, also known as regular reflection, is the mirror-like reflection of waves, such as light, from a surface.

DIFFUSE REFLECTION OCCURS FROM ROUGH SURFACES AND NO CLEAR IMAGE IS FORMED

Diffuse reflection is uniform reflection of light with no directional dependence for the viewer, e.g., a matte surface such as cardboard.

THE LAW STATING THAT LIGHT IS REFLECTED AT THE SAME ANGLE THAT IT IS INCIDENT OR i=r

The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane.

A FLAT MIRROR.

THE FIRST ANSWER

THE SIDEWAYS OF LEFT-TO-RIGHT REVERSAL OF AN IMAGE IN A PLANE MIRROR.

THE FIRST ANSWER

AN IMAGE FORMED IN WHICH THE RAYS OF LIGHT DO NOT ACTUALLY MEET, BUT ONLY APPEAR TO MEET AT A POINT INSIDE THE MIRROR
