Step-by-step explanation:
Answer:
intensity =
intensity =
depth = 333.33 m
Step-by-step explanation:
given data
deep = 10 m
intensity = Io
intensity = Io/3
to find out
intensity of light at 50 m and 100 m and 1/100 of initial intensity remain ?
solution
we know here that intensity is inversely proportional to deep so
intensity = k ×
.................1
here k is constant
so we have given 10 m deep so
= 
so k = Io ×
................2
so from equation 1 when 100 m deep and 50 m deep
intensity = k ×
intensity = Io ×
×
intensity =
and
intensity = Io ×
×
intensity =
and
at intensity Io/100
intensity = k ×
= Io ×
×
D = 333.33 m
so depth = 333.33 m
Answer:
Proof in explanation.
Step-by-step explanation:
I'm going to attempt this by squeeze theorem.
We know that
is a variable number between -1 and 1 (inclusive).
This means that
.
for all value
. So if we multiply all sides of our inequality by this, it will not effect the direction of the inequalities.

By squeeze theorem, if 
and
, then we can also conclude that
.
So we can actually evaluate the "if" limits pretty easily since both are continuous and exist at
.

.
We can finally conclude that
by squeeze theorem.
Some people call this sandwich theorem.
