Answer 1

QUESTION.
What is the relationship between the frequency of light and its color?



ANSWER .


we understand it by electromagnetic spectrum .


ELECTROMAGNETIC SPECTRUM.

The ordinary distribution of electromagnetic radiations according to their wavelength or frequency called ELECTROMAGNETIC SPECTRUM.


SOME IMPORTANT POINT ABOUT ELECTROMAGNETIC SPECTRUM .


1 TYPE OF WAVE IN THE SPECTRUM.

1 RADIO WAVE

2. MICRO WAVE

3 INFRARED WAVE

4 VISIBLE. WAVE

5 ULTRA WAVE

6. X - RAYS

7 GAMMA RAYS


NOTE .

As we know frequency is inversely proportional to the wavelength .

=> if frequency is more then wavelength is least.

so in spectrum Radio wave have highest wavelength and then decrease top to bottom .
so it's frequency is least .

NOW ON MAIN POINT .

As we know Only small

part of electromagnetic spectrum is visible to human eye , as the radiation of this part can produce sensation on our retina of eye .

This part of spectrum is called VISIBLE SPECTRUM .



NOTE .

The radiation of different wavelengths in visible paery of spectrum produce. different. colour on retina of eye .


REALATION BETWEEN FREQUENCY AND COLOUR .

if frequency is greater then it more violet and if frequency is lower then it more be red .


similarly in wavelength lower the wavelength it become more violet and greater the wavelength it become more red

=> RED COLOUR HAVE LOWEST FREQUENCY AND GREATER WAVELENGTH

AND VIOLET HAVE HIGHEST FREQUENCY AND LOWEST WAVELENGTH .


COLOUR WHICH ARE PRODUCED SANSATION ON RETINA


VIBGYOR



1 violet. 2. indigo. 3. blue. 4 green

5 yellow. 6. orange. 7 red
