Light - it has different colours ( The Vedas)

Rigveda 6th anuvakam, 30th hymn 20,21,22 verses

कस्त उषः कधप्रिये भुजे मर्तो अमर्त्ये कं नक्षसे विभावरि

वयं हि ते अमन्मह्यान्तादा पराकात अश्वे न चित्रे अरुषि

तवं तयेभिरा गहि वाजेभिर्दुहितर्दिवः अस्मे रयिं निधारय

Meaning:

"Oh! everlasting light!is there anyone who cannot enjoy your presence?is anyone who can reach you?oh! Usho devi ( name of goddess of light ) you have so many colours.Their spreading finamina is great.It is impossible to enjoy your light from near or far.Your are the daughter of "Dyulokam(world of light)""

Here in this meaning we can easily know that light is having not only white colour but somany colours.So this finamina of light is known to our saints of Vedic age.So this is not a new invention as we are thinking that this finamina is invented by western scientists.

The Ozone and Atmosphere in Vedas

The following are of Rigveda, 6th anuvaka,24 th hymn and 6,7 verses
नहि ते कषत्रं न सहो न मन्युं वयश्चनामी पतयन्त आपुः
नेमा आपो अनिमिषं चरन्तीर्न ये वातस्य परमिनन्त्यभ्वम

अबुध्ने राजा वरुणो वनस्योर्ध्वं सतूपं ददते पूतदक्षः
नीचीना सथुरुपरि बुध्न एषामस्मे अन्तर्निहिताःकेतवः सयुः
Meaning:
"Oh Varuna you are very known for your strengthness.Neither of birds and ever flowing water can reach you .Varuna are the king.He is in space which has no base.There He wears a luminous queen.His rays are passing from upper space to earth.The origin of those rays is in space only.Thatswhy our lives are survived."

If we think deep about these verses we can easily know that here Atmosphere is denoted as Varuna and the ozone layer is denoted as the luminous queen.If you see the last line of the second verse we know that" rays are passing to the earth and our lives are being survived".
The space originated rays are purified before reaching the earth.otherwise we cannot live.

The Water therapy in Vedas

The following are of the Rigvedam,5th anuvakam,23rd hymn, 19,20,21 verses

अप्स्वन्तरम्र्तमप्सु भेषजमपामुत परशस्तये देवाभवत वाजिनः

अप्सु मे सोमो अब्रवीदन्तर्विश्वानि भेषजा अग्निं च विश्वशम्भुवमापश्च विश्वभेषजीः

आपः पर्णीत भेषजं वरूथं तन्वे मम जयोक च सूर्यं दर्शे

The above three hymns in rigveda mean that

"There is nector in water.All medicines are there in the water.Know the importance of the water and make this matter to public.Soma says there is fire,which helps us a lot,is in the water .May the water cure all diseases of our bodies and may they help us to see the sun for ages(to live for many years)".

Many of people think that " The water therapy" is discovered in last 100 years only.But if you read above verses we can say that this "Water therapy" is known in vedic age itself.
