1. THE SPEED OF LIGHT THE SPEED OF ELECTROMAGNETIC WAVE
This presentation is about how
THE SPEED OF LIGHT
THE SPEED OF ELECTROMAGNETIC WAVE
THE HIGHEST SPEED IN THE UNIVERSE
That is km/sec.
Can be determined / calculated exactly based on
The information taken from an old document

2. Perhaps you have ever known that the constant C, or the speed of light that is the highest speed in the universe has been calculated, measured or determined by the institutions below:
US National Bureau of Standards
C = km/sec
The British National Physical Laboratory
C = km/sec
17th conference on measurements and weight standards
”one metre is the distance reached by the light in vacuum in 1/ sec".

3. The holy Qur’an, the holy book of Islam
But you should know that the constant C can be determined / calculated using the information taken from a holy book sent down 14 centuries ago..
The holy Qur’an, the holy book of Islam
The inventor of this calculation is a physicist from Egypt, DR. Mansour Hassab El Naby

4. It is told in the holy Qur’an:
”It is He (ALLAH) who made the sun to be a shinning glory and the moon to be a light (of beauty), and measured out stages for it, that ye might know the number of years and the count (of time)”- (10:5)
”It is He (ALLAH) who created the Night and the Day, and the sun and the moon: All (the celestial bodies) swim along, each in its rounded course“ – (21:33)
“He directs the affairs from the heavens to the earth: then it ascends unto Him, on a Day the measure of which is a thousand years of your reckoning” (32:5)

5. C . t = 12000 . L The distance reached by The affairs in a day
Based on verses, mainly the last verse (verse 32:5) it can be concluded that:
The distance reached by The affairs in a day
is equal to
The distance reached by the moon in 1000 years or months
C . t = L
where : C = the speed of the Affairs
t = time in a day
L = the route length of the moon’s trip in one month

6. There are two month calendar systems:
Many calender systems, has been tested,
But only “sidereal month calendar system” produce the value C
Which equal to the value of C based on measurement
There are two month calendar systems:
1. Sinodic System, based on virtual apparition of
moon’s and sun’s motions from the earth.
1 day = 24 hours
1 month = days
2. Sidereal System, based on relative motion of
the moon’s and the sun to the star in universe.
1 day = 23 hours 56 minutes seconds
= seconds
1 month = days

7. This simulation is given to show you the difference between sidereal month and the sinodic
Consider the moon’s position after
29.52 days
The moon position !  o
The period time
360o revolution moon = o revolution earth
This period in days or hours.
And it is called “One sidereal moon”
The moon go back to initial position exactly in line between the sun and the earth. This period is called “one sinodic moon”  o

8. L = v. T Then consider the moon’s route during one sidereal month
The route is not of a circle like you possibly imagine
But in the form of a curvature with a length of L = v . T L
= v. T
where:
v = the speed of the moon
T = moon revolution period
= days  o
days
days
* 360o
= o
 =

9. A Note on the speed of moon (v)
There are two types of moon’s speed :
1. Relative speed to earth which can be calculated with
the following formula:
ve = 2 .  . R / T
where R = radius of moon revolution = km
T = the period of moon’s revolution = hours
Hence ve = 2 * * km / hrs
= km/hr
2. Relative speed to star or universe. This is what we need
Albert Einstein proposed that this type of speed can be calculated by doing a multiplication of the first with cosine , so that:
v = Ve * Cos 
Where  is the angle formed by earth’s revolution during one sidereal month
 = o

10. Remember !
L = v . T
Hence:
C . t = L
Remember !
v = ve . Cos 
C . t = v . T
Remember !
ve = km/hr
 = o
T = hrs
t = sec
C . t = ( ve . Cos  ) . T
C = ve . Cos  . T / t
C = * km/hr * * hrs / sec
C = km/sec

11. The C calculated The C measured
Compare the C (the speed of the Affairs) as the result of this calculation with the C (the speed of light) which has been known !
The C calculated
C = km/sec
The C measured
US National Bureau of Standards
C = km/sec
The British National
Physical Laboratory
C = km/sec
17th conference on
measurement and weight standard
“One meter is a distance reached by the light in vacuum in 1/ seconds"

12. In the name of Allah, Most Gracious, Most Merciful
The holy Qur’an 32: 1-5
In the name of Allah, Most Gracious, Most Merciful
Alif Lam Mim. (This is) the revelation of the Book in which there is no doubt, from the Lord of the Worlds
Or do they say “he (Mohammed) has forged it ?”, Nay, it is the Truth from thy Lord that thou mayest admonish a people to whom no warner has come before thee : in order that they may be rightly guided.
It is Allah Who has created the heavens and the earth, and all between them, in six Days. Then He established Himself on the Throne: Ye have none, besides him, to protect or intercede (for you) . Will ye not then receive admonition ?
He directs the affairs from the heavens to the earth: then it ascends unto Him, on a Day the measure of which is a thousand years of your reckoning

13. The conclusion
(from the article of Prof Elnaby)
“This calculation proved the accuracy and consistency of the constant C resulted from measurement and also shows the truth of the Holy Qur’an as revelation which is proper to be studied with a sharp analysis for the Writer is the Creator of the universe”
