00:00:01.000 --> 00:00:05.730 A:middle L:90%
the refractive index off the quartz begin by the speed
2
00:00:05.730 --> 00:00:10.289 A:middle L:90%
of light in the vacuum or their velocity off light
3
00:00:10.300 --> 00:00:14.880 A:middle L:90%
inside. That medium speed off light is we know
4
00:00:14.880 --> 00:00:19.969 A:middle L:90%
is ah three point old times 10 to the gate
5
00:00:20.019 --> 00:00:25.250 A:middle L:90%
into the eight meters per second and over us b
6
00:00:25.250 --> 00:00:30.359 A:middle L:90%
which is given here we have 1.94 Dienst end to
7
00:00:30.359 --> 00:00:34.929 A:middle L:90%
the power ate it ended power eight meter. So
8
00:00:34.929 --> 00:00:37.170 A:middle L:90%
this gives us a refractor. Next off reports,
9
00:00:37.170 --> 00:00:43.560 A:middle L:90%
which is 1.54 This is spot A Barbie. We
10
00:00:43.560 --> 00:00:48.600 A:middle L:90%
are asked to find What is Linda nods the rev
11
00:00:48.600 --> 00:00:54.810 A:middle L:90%
Lint inside the quartz which, um, this is
12
00:00:54.810 --> 00:00:57.039 A:middle L:90%
not the welland inside the quartz. Rather, it's
13
00:00:57.039 --> 00:01:02.310 A:middle L:90%
the prevalent off the light in video air. So
14
00:01:02.310 --> 00:01:04.500 A:middle L:90%
let me distract Lemon Dolly. So Lamda is equal
15
00:01:04.500 --> 00:01:08.010 A:middle L:90%
toe end times. Let the Lord story is equal
16
00:01:08.010 --> 00:01:11.920 A:middle L:90%
to early guys. Linda, that is equal to
17
00:01:11.920 --> 00:01:15.650 A:middle L:90%
1.5 for affecting if we got here this times.
18
00:01:15.909 --> 00:01:22.319 A:middle L:90%
Um, so if the light travels through air,
19
00:01:22.319 --> 00:01:26.510 A:middle L:90%
what easy. It's rebelling. So then, um
20
00:01:26.519 --> 00:01:33.689 A:middle L:90%
, we have the prevalent will be given by reflecting
21
00:01:33.689 --> 00:01:38.400 A:middle L:90%
next time's the prevalent off light inside the quartz,
22
00:01:38.400 --> 00:01:44.250 A:middle L:90%
which is 3.55 10 to the power minus seven meters
23
00:01:44.739 --> 00:01:49.000 A:middle L:90%
. And this gives us the welland which is 5.47
24
00:01:49.000 --> 00:01:53.230 A:middle L:90%
times 10 to the power into the power minus seven
25
00:01:53.230 --> 00:01:57.310 A:middle L:90%
meters. End off the problem. Thank you for
