Answer: 45° and speed of light in prism 2×10⁸m/s
Step-by-step explanation:
The minimum deviation of the equilateral glass prism will form 60° angle.
So angle of incidence = 3/4×60
= 3 ×15
= 45°
Minimum deviation = δmin
= 30
After finding the value of μ using prism law
μ = 1.41
Speed of light will be 2×10⁸m/s

Answer: -4/5 or -0.8
Step-by-step explanation:
m= change in y / change in x
-4/ 5
Answer:
x = 50°
Step-by-step explanation:
180° - 80° = 100°
100° ÷ 2 = 50°
50° + 50° + 80° = 180°
Answer:
your answer should be -4/5
