Hi, student.
00:01
Welcome to the solution of the problem.
00:03
First of all, thanks for posting the problem.
00:07
It's about electromagnetic radiations and out of the given options, we have to find which radiation has the highest energy.
00:15
Now, the energy of an electromagnetic radiation is actually inversely proportional to its wavelength.
00:24
So what we will do is we'll find the wavelengths of all these given radiations and, this we will conclude which one has the highest energy.
00:35
Now the radio waves have wavelength of the order of 10 raise to 2 meters.
00:44
Microwave has a wavelength of the order of 10 raise to minus 2 meters.
00:51
For the time being we'll consider indigo and green to be common as visible radiations and they range from 4 times 10 rise to minus 7 meter to 7 times 10 rise to minus 7 meter.
01:08
Infrared radiation 10 rise to minus 4 meter.
01:12
From this it is very clear that either indigo or green is the answer...
