Answer 2

The angle of refraction for this ray in the glass​ is 25 degrees

Solution:

The refractive index is given as:

$n = \frac{sin\ i }{sin\ r}$

Where,

"n" is the refractive index

"i" is the angle of incidence

"r" is the angle of refraction

From given,

$i = 40^{\circ}\\\\n = 1.5\\\\r = ?$

Substituting the values we get,

$1.5 = \frac{sin\ 40}{sin\ r}\\\\sin\ r = \frac{sin\ 40}{1.5}\\\\sin\ r = \frac{0.64278}{1.5}\\\\sin\ r = 0.42852\\\\r = sin^{-1} 0.42852\\\\r = 25.3736\\\\ r \approx 25^{\circ}$

Thus angle of refraction for this ray in the glass​ is 25 degrees
