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
