0:00
Right.
00:01
So for this question, we'll ask which has higher frequency, infrared or uv, and which one has longer wavelength, which one has greater energy.
00:09
All right, before we started, i want us to first figure out the equation.
00:14
Remember the two equations.
00:15
E equal to hv.
00:18
V here is stand for frequency.
00:20
This is frequency.
00:25
Okay.
00:25
This is q, by the way.
00:27
Sorry about that.
00:28
The next equation that you want to remember is c is equal to lambda v.
00:33
Now why i'm talking about this, because there is a relationship.
00:35
As e increases, the v over the frequency, new, is also increases.
00:42
Now, on the other hand, if frequency increases, the wavelengths go down.
00:48
Okay, by the way, lambda is then for wavelength.
00:50
So you can see that's what is happening.
00:53
So they have direct relationship, inverse relationship.
00:56
You want to know that.
00:57
The next piece of information you want to know is the color of the rainbow, the visible spectrum, rogyvid, r -o -y -g -b -i -v.
01:08
In this case, they don't really ask for rojivit, but they ask for extension of this...
