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:
Step-by-step explanation:
18x-6=120
18x=120+6
18x=126
x=126÷18
x=7
<h2>
Answer: (3/2)x - 2</h2>
Step-by-step explanation:
Let the number be x.
"Two less than 3/2 of a number (x)" means (3/2)x - 2
"is no more than" means "≤"
5 1/2
