Speed of Light was well known in Ancient Bharath, Acharya Sayana in his commentary on Rigveda 1.50.4 s
Mentions It.
He says,
"It is to be remembered that light from the sun travels 2202 Yojanas in half a Nimisha"

This Yojana and Nimisha are ancient units if Measurements, I will convert them to modern measurements here.
According to Manusmriti 1.64
18 Nimesha = 1Kastha
30 Kastha = 1 Kala
30 Kala = 1 Muhurta
30 Muhurta = 24 hours
According to Manusmriti 1.64
18 Nimesha = 1Kastha
30 Kastha = 1 Kala
30 Kala = 1 Muhurta
30 Muhurta = 24 hours
Hence I Nimisha = 0.1777777778s
And Half Nimisha = 0.088888889s
Now Yojana it is generally taken as 8 Miles but that's an error, because it was used to measure distances on land and due to error in measurement and comparison the value should be 7.5 miles.
And Half Nimisha = 0.088888889s
Now Yojana it is generally taken as 8 Miles but that's an error, because it was used to measure distances on land and due to error in measurement and comparison the value should be 7.5 miles.
Same thing said by Alexander Cunningham In his Ancient Geography of India
Hence light travels 2202×7.5 miles in 0.888888889 seconds the result is
= 185793.7499.. Miles per second
Modern Measurement = 186282 miles per second
Hence light travels 2202×7.5 miles in 0.888888889 seconds the result is
= 185793.7499.. Miles per second
Modern Measurement = 186282 miles per second
Very close considering Yojana is a Approximation and not exact.
So it is proved that Ancients knew speed of light
