## Critical Angle and Total Internal Reflection of Light

Dear students, we have learnt about refraction of light from rare medium to denser medium and vice versa.You know that angle of refraction of light depends on angle of incidence. Greater the angle of incidence, greater will be angle of refraction generally. If we perform an experiment, we may observe Read more…
