.
Plz solve it fast

Answer 1

the answer is 1.760^108m/s

Answer 2

Hey dear,


● Answer -
v = 1.77×10^8 m/s

● Explanation -
# Given -
μ = 1.7
c = 3×10^8 m/s

# Solution -
Refractive index of ruby is given by -
μ = c / v

Rearranging for v,
v = c / μ
v = 3×10^8 / 1.7
v = 1.77×10^8 m/s

Therefore, speed of light through ruby is 1.77×10^8 m/s.

Hope this helps you...
