the seven light are : red,orange,yellow,green,blue,indig o,violet 1 seeing the colored transparent objects: the transparent and translucent object allow light to pass through them so, the color of the transparent and translucent object is the same color of the transmitted light through them
example: when you look at this glass bottle it seems green in color 2 seeing the colored opaque object:the opaque object are divided into : a white obeject b black obeject c colored object a seeing the white opaque object when white light strikes the white opaque object this object reflects all the light color so, the white opaque body appears with the same color of the light that falls on it b seeing the black opaque object : when white light steikes the black opaqueobject this object absorbs all the light color so the black object absorbs any light falls on it c seeing the colored opaque object when the white light strikes the colored opaque object it absorbs all the light colors and reflects its own color only
so,the color of the opaque object is the color of the reflected light three color spots are formed where ,red,green,blue color primary colored lights the secondarycolored light are yellow ,magenta,cyan what have you learnt the apple appears red ,because it absorbs all the light color that falls on it and reflects the red light only the reflected red light strikes the red light strikes the red transparent glass sheet and transmits through it then reaches our eyes the apple appears black ,because the reflected red light from the apple doesnt transmit through green and blue glass sheets
