Hi there.
00:02
So for this problem, we need to calculate the wavelength in some mediums.
00:08
In the first part, we are given that the wavelength in earth is 589 nanometers, and we want to cultivate the wavelength when it is traveling in diamond, which has a reflective index of 2 .419.
00:27
So to obtain this, we use the following.
00:30
Formula, the wavelength in the median is equal to the velocity in the median over the frequency.
00:43
In this case, the frequency is defined as the speed of light over the wavelength in air, and the velocity in the medium is defined as the speed of light over the index of of refraction.
01:08
So when we just did this into that formula, we obtained the following.
01:20
We can console this and we are going to obtain that the wavelength in the median is given by the wavelength in earth over the index of refraption.
01:35
So we just simply need to substitute those values to obtain the wavelength in the wayflaping in the index of refraption.
01:41
The given median, in this case in diamond...
