Answer:
The angular separation between the red and violet components of the spectrum that emerges from the glass is 1.72°
Explanation:
Given:
Refractive index for red light
Refractive index for violet
Refractive index for air
Incident angle 28.30°
According to the snell's law,
For red light,
Where transmitted angle for red light
50.18°
For violet light,
Where transmitted angle for violet light
51.9°
Angular separation between red and violet light is given by,
1.72°
Therefore, the angular separation between the red and violet components of the spectrum that emerges from the glass is 1.72°
