Question

How do you verify experimentally that the value of sin i /sin r is

constant? do follow for more questions ​

Answer 1

Answer:

Draw two NN (Normal) lines at points marked 1 and 2 in your reference books or books from which you asked this questuon. Measure angles i1, r1, i2, and r2 by a protractor. Use i1 and r1 and the Snells formula to find n, which is the refraction index of the glass slab. Use i2 and r2to find n again. After some simplification, you get the answer. HENCE PROVED.
