Challenge Problems
Push your limits with challenges.
Question 1
Given that the angle of incidence is 45 degrees and the angle of refraction is 30 degrees, calculate the refractive index of the second medium. Show your working.
💡 Hint: Use the relationship of angles and sine values.
Question 2
If light travels from air (n=1.00) into water (n=1.33) at an angle of incidence of 60 degrees, what is the angle of refraction?
💡 Hint: Remember to rearrange Snell's Law according to the formula.
