Calculate the speed of light in glass
O A A day of light enters a rectangular glass s
slab of refractive enden 1.5. i fes found
that the day emerges from the opposite
fore of the slab without being displaced
If its speed ein ais és 3x108 anst then what
es its speed en glass?
The speed of light ona transparent medium
is 0.6 times that of its speed invandrum
what is the sa fractive inden of the medium?​

Answer 1

Answer:

8 men =12 women ⇒ 4 men =6 women

∴ 4 men +4 women =6 women +4 women =10 women

Given, 12 women can do a piece of work in 10 days

⇒ 1 women can do the same work in (12×10) days

⇒ 10 women can do the same work in

10

12×10

days =12 days.
