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:I got 33 and 34
Explanation:
Call your integers n and n+1 we get:
n+n+1= 67
rearrange:
2n = 66
n=66/2 = 33
The integers will be 33 and 34
Answer:
74°
Step-by-step explanation:
m(arc)JKL = 2 × 99° = 198°
8x - 6 + 12x + 4 = 198
20x - 2 = 198
20x = 200
x = 10
m(arc)KJ = 8x - 6 = 8(10) - 6 = 74°
