In this problem, we have been given certain types of radiations and it also includes sound waves.
00:08
And we have to arrange only the electromagnetic radiations out of these given things here.
00:15
And that needs to be arranged from the longest wavelength to the shortest wavelength.
00:21
So let's write here on the left with longest wavelength.
00:25
And on the right, this will be odd.
00:27
Let's take at the bottom the shortest wavelength.
00:31
So as we know, the electromagnetic radiations out of them, it excludes the sound wave and rest all are electromagnetic waves.
00:42
They are a part of electromagnetic waves.
00:45
So we see here that electromagnetic waves that contains seven kinds of radiations, one is gamma, another one is x -ray, and then we have ultraviolet rays, and then we have the visible spectrum, which includes all the colors.
01:02
From violet to the red.
01:05
And also this electromagnetic radiations, it includes infrared rays, it includes microwaves and then the radio waves.
01:15
So these are arranged such that as we go to the right, the wavelength is likely to increase...
