Answer:
therefore critical angle c= 69.79°
Explanation:
Canola oil is less dense than water, so it floats over water.
Given
which is higher than that of water
refractive index of water
to calculate critical angle of light going from the oil into water
we know that
now putting values we get
c=
c=69.79°
therefore critical angle c= 69.79°
