Question

In Part 5.2.3 of the experiment, you will measure the index of refraction of yellow light using Lab Manual Equation 5.2. Suppose the minimum angle of deviation is 18 degrees. What is the index of refraction

Answer 1

Answer:

The answer is "1.26".

Explanation:

$D=18^{\circ}$

The refractive index is:

$\to \mu=2\sin(30^{\circ}+\frac{D}{2})$

       $=2\sin(30^{\circ}+\frac{18^{\circ}}{2})\\\\=2\sin(30^{\circ}+9^{\circ})\\\\=2\sin(30^{\circ}+9^{\circ})\\\\=2\sin(39^{\circ})\\\\=2 \times 0.63\\\\=1.26$
