Question

how to find angle of emergernce ​

Answer 1

Measure it with a protractor with reference to the normal. If the medium has parallel sides, the angle of incidence will be equal to angle of emergence

hope this helps

Answer 2

Explanation:

Is there a way to calculate emergent angle of an equilateral prism (non-experimentally) ? I know that one equation that might be helpful is

∠D+∠A=∠i+∠e

But a single equation isn't enough to calculate the emergent angle. Given data is : Refractive index of prism (μ), Angle of prism(∠A)& angle of incidence (∠i)
