Is Danish astronomer ole Roemer really first person who measure the SPEED OF LIGHT? (1644-1710)
--Who describes first velocity of light first?
RIGVED ...
Let's see how ...?
प्रकाश की गति (Velocity of Light)
सूर्य-विषयक ऋग्वेद में एक मंत्र 'तरणिर्विश्वदर्शत:
ऋग्० १.५०.४
च स्मर्यते - योजनां सहस्रे द्वे द्वे शते द्वेच योजन । एकन निमिषार्धेन क्रमांकमाण नमोस्तु ते ..
ऋग्वेद 1.500 मंत्र की निरूपण
अर्थात् हे सूर्यतुम्हारी गति आधे निमेष ( पलक मारना) में दो हजार दो सौ दो (२२०२) योजन है। सूर्य की किरणों कि गति कितनी तीव्र है, निमेष क्या है
काल ज्ञान के लिए महाभारत का निम्नलिखित श्लोक बहुत महत्त्वपूर्ण है ।
काष्ठा निमेषा दश पञ्च चैव,
त्रिंशत् तु काष्ठा गणयेत् कलां ताम् ।
त्रिंशत् कलाश्चापि भवेन्मुहूर्तो
भागः कलाया दशमश्च यः स्यात् ।
त्रिंशन्मुहूर्तं तु भवेदहश्च ।
(महा शान्तिपर्व अध्याय २३१ श्लोक १२ और १३)
Now see what his theory says
It was the Danish astronomer, Olaus Roemer, who, in 1676, first successfully measured the speed of light. His method was based on observations of the eclipses of the moons of Jupiter
Roemer noted that the observed time interval
between successive eclipses of a given moon was about seven minutes greater when the observations were carried out when the earth in its orbit was moving away from Jupiter than when it was moving toward Jupiter. He reasoned that, when the earth was moving away from Jupiter, the
