Question

which among the following monochromatic light has more frequencya. red b. green c. yellow d .blue

Answer 1

Red has the more frequency.. As it can be noticed from far off places...

Answer 2

Frequency is inversely proportional to wavelength. (lambda×neu=c)

As red light has highest wave length so its frequency will be least.

Also blue has least wavelength so its frequency will be most.

So here decreasing trend of frequency is -

Blue>green>yellow>red...

Hope this will help..
