the red apple is seen red because it absorbs all the colors of light that strike it and
.reflects the red one only .when the reflected red light bouncing back from the apple
.it strikes the red glass sheet, the red light transmits through the glass and reaches
.the eyes so you see the apple in red.
.When you look at the red apple through the green glass sheet, you will find that the
.green glass sheet doesn’t transmit the reflected red color bouncing back from the apple. .so the apple will appear with no color and seen to be black.
.you will get same result in case of using the blue glass sheet, too.
Thank! .What color is a piece of paper stuck by light transmitting though an orange glass sheet?
MIXING THE COLORED LIGHT
To study the effect of mixing the colored light we use three colored projector sets:
One produces red Light, the second produces green light and the third gives blue
When the three sets send out the light on a white screen, you will get three circular
Light spots: red, green and blue as indicated below.
_THE SEVEN LIGHT COLORS ARE:

Red, orange, yellow, green, indigo, violet
- When the seven light colors and mixed together, the white light is produced.
ACTIVITY
TOOLS: APIECE OF CONSTRUCTION WHITE PAPER_COLORS_SCISSORS_A PROTRACTOR.
STEPS: 1.CUT THE CONSTRUCION PAPER IN A SHAPE OF A DIVIDE BY USING SCISSORS.
2. Divide the disk into seven equal parts by using the protractor.
3. Color the disk with the same order of spectrum colors.
4. Bore a small hole at the center of the disk then pass your pencil through it.
5. Rotate the disk quickly.
Observation:-
THE SEVEN LIGHT COLORS ARE:

Red, orange, yellow, green, indigo, violet
- When the seven light colors and mixed together, the white light is produced.
