Answer:
Sue = 25.75
Dave = 29.5
Tom = 19.75
Sue = s
Tom = t
Dave = d
Step-by-step explanation:
s+t+d = 75
s-6=t
d +16 = s+t
d+16+d= 75
2d = 59
d = 29.5
t = s-6
t+s = 45.5
s-6+s= 45.5
2s = 51.5
s= 25.75
t= 19.75

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
