00:00:00.340 --> 00:00:03.350 A:middle L:90%
in this problem. Ah, Ray off light strikes
2
00:00:03.350 --> 00:00:07.000 A:middle L:90%
the one side off the surface off the equal,
3
00:00:07.000 --> 00:00:13.089 A:middle L:90%
literal prison that strikes here and then right of facts
4
00:00:14.039 --> 00:00:16.719 A:middle L:90%
goes here, and then it emerges out of prison
5
00:00:17.940 --> 00:00:21.550 A:middle L:90%
. Uh, the angle it makes with prism here
6
00:00:22.239 --> 00:00:24.809 A:middle L:90%
, which we call it a theta one, which
7
00:00:24.809 --> 00:00:28.760 A:middle L:90%
is equal to 30 degrees. And, uh,
8
00:00:30.390 --> 00:00:33.350 A:middle L:90%
the other angle here that we call it all for
9
00:00:34.200 --> 00:00:37.869 A:middle L:90%
And this angle is six degrees, and this one
10
00:00:37.880 --> 00:00:44.710 A:middle L:90%
is better. Um, this angle is in 30
11
00:00:45.100 --> 00:00:51.049 A:middle L:90%
in all three and angle too, is here,
12
00:00:52.939 --> 00:00:58.409 A:middle L:90%
which is a 40.53 degrees and angle. One is
13
00:00:58.409 --> 00:01:03.109 A:middle L:90%
here, and the moon, which is 19.40 70
14
00:01:03.120 --> 00:01:08.409 A:middle L:90%
degrees from snails all weaken the soulful. But here
15
00:01:08.409 --> 00:01:14.180 A:middle L:90%
they're just times Sign that a one. There is
16
00:01:14.180 --> 00:01:19.390 A:middle L:90%
a folder in two times, scientist too. Premiere
17
00:01:19.390 --> 00:01:22.000 A:middle L:90%
. We know that in one is equal to their
18
00:01:22.439 --> 00:01:26.689 A:middle L:90%
medium. Here is ah, here. Therefore they're
19
00:01:26.700 --> 00:01:30.310 A:middle L:90%
perfecting next for the that medium. This one and
20
00:01:30.310 --> 00:01:34.000 A:middle L:90%
for into their effectiveness is 1.5 for the glass off
21
00:01:34.000 --> 00:01:38.530 A:middle L:90%
the prison. And that the one we have is
22
00:01:38.530 --> 00:01:42.040 A:middle L:90%
the 30 degrees. Then we can subdue those values
23
00:01:42.040 --> 00:01:46.349 A:middle L:90%
for the above equation. Then we can write.
24
00:01:46.349 --> 00:01:49.980 A:middle L:90%
Sign that one s or these are 30 Parisi physical
25
00:01:49.980 --> 00:01:56.939 A:middle L:90%
to 1.5 dime side they don't want from here they're
26
00:01:56.939 --> 00:02:00.750 A:middle L:90%
the one will be equal Thio signed in worse off
27
00:02:00.340 --> 00:02:06.090 A:middle L:90%
sign 30 degrees divided by 1.5. This gives us
28
00:02:06.090 --> 00:02:07.659 A:middle L:90%
an angle one that a wonder is a part of
29
00:02:07.659 --> 00:02:15.120 A:middle L:90%
19.47 degrees. Then from the figure here from this
30
00:02:15.120 --> 00:02:20.750 A:middle L:90%
figure, we can, uh, find also also
31
00:02:20.750 --> 00:02:25.729 A:middle L:90%
will be 19 minus 19.47 degrees. And the better
32
00:02:25.729 --> 00:02:31.979 A:middle L:90%
we can write better will be 1 80 minus 90
33
00:02:32.189 --> 00:02:43.550 A:middle L:90%
minus 19.47 minus 60. This gives us better 49.47
34
00:02:44.599 --> 00:02:46.189 A:middle L:90%
From here, we can write in. The two
35
00:02:46.189 --> 00:02:50.039 A:middle L:90%
will be equal to 90 minus better, which is
36
00:02:50.039 --> 00:02:58.409 A:middle L:90%
a cult of 19 minus 49.47 which uses 40.53 We
37
00:02:58.409 --> 00:03:02.620 A:middle L:90%
apply Snell's law for a fraction off the interference on
38
00:03:02.620 --> 00:03:07.120 A:middle L:90%
the left side of prism we're and one is equal
39
00:03:07.120 --> 00:03:12.759 A:middle L:90%
to 1.5 and there's no one is equal to 40.53
40
00:03:13.460 --> 00:03:17.090 A:middle L:90%
in two is equal to one that a two intercooled
41
00:03:17.099 --> 00:03:22.330 A:middle L:90%
2 33 Using his left so we can find a
42
00:03:22.340 --> 00:03:23.909 A:middle L:90%
data. Three. Is it called a sign in
43
00:03:23.909 --> 00:03:30.409 A:middle L:90%
Warsaw for 1.5 times. Sorry, 40.53 This gives
44
00:03:30.409 --> 00:03:38.099 A:middle L:90%
us 77.1 degrees, but be we know from the
45
00:03:38.099 --> 00:03:44.590 A:middle L:90%
loft reflection that is angle off incident that the incident
46
00:03:44.599 --> 00:03:50.259 A:middle L:90%
is equal to the angle off refraction reflection story at
47
00:03:50.270 --> 00:03:53.330 A:middle L:90%
the right service than in the lawful reflection. One
48
00:03:53.330 --> 00:04:00.849 A:middle L:90%
is 30 degrees that the left surface left surface we
49
00:04:00.849 --> 00:04:04.250 A:middle L:90%
have that are too is equal to the two,
50
00:04:04.569 --> 00:04:09.750 A:middle L:90%
which is about 40.5 three degrees.
