  W hat are the seven colors of light ? Generally, we know that the light is a thing that helps us to see but according to physics, light has both wave and particle nature (wave-particle duality), so it is an electromagnetic radiation within the part of the electromagnetic spectrum which can be seen by human eye. (Dispersion through Prism)          The white visible light is a mixture of seven different colors, which was first discovered by Sir Isaac Newton. He discovered this in 1666, when he passed a beam of white light through a prism and identified these seven colours, which are violet, indigo, blue, green, yellow, orange and red (shortly VIBGYOR). This method is called as dispersion, because when white light is divided into its constituent colors, it is called dispersion. Why are white light and black (or dark) not the colors of light ? :-          White light is a mixture of seven different colors and all these colors have di...

  About the Universe of 10 Dimensions of String Theory. Normally, we read about many higher dimensions in mathematics, but do you know how many dimensions exist in the universe? In physics, many theories explain their various number of dimensions. According to M-Theory , Bosonic String Theory and current String Theory (or Superstring Theory ), there are 11, 26 and 10 dimensions respectively. Like this, in Hinduism, it is mentioned that there are 64 dimensions in the universe. Some Information about the Dimension :-         Although we know that the fourth dimension is time according to the General Theory of Relativity and Quantum Physics , but still we don't know many things about it, because we are made up of 3-D, and we also live in a 3-dimensional world. According to scientists, we can go to every dimension and feel them, if we can convert our body into one dimension and make our body so small, which will be many times smaller than electrons, protons or ne...

  Why does sea water look blue ? (Blue water in the Sea)         Small amounts of water look colorless and large amounts of water are also colorless and clean, as water is always colorless but there are some reasons why large amounts of water look blue such as lakes, seas and swimming pools. We all know that there is no color of water but still the water of sea, lake and swimming pool looks blue. Why does this happen ? Let's come to know some scientific reasons behind it.         Actually, the color of pure water is very slightly blue, therefore, it looks blue when we increase its thickness and volume. So, this is the reason why swimming pool water and sea water look blue.         Now, coming to the 2nd reason, we know that water has no color and it is clean but when a light falls on it, it reflects that light easily. So, we can say that blue color of sea is also due to reflection of sky, since sky is blue. ...

Similarity and Difference between Light and Sound.   (Light and Sound Waves) Similarity :-  (1)👉  Both light and sound are forms of energy. (2)👉 They both have wave nature. (3)👉 Both light and sound have properties of wavelength, frequency and amplitude. (4)👉 The reflection laws of light and sound are same. i.e.–           (I) The angle of reflection is equal to the angle of incidence.          (II) The reflected sound ( reflected ray for light), the incident sound (incident ray for light) and the normal belong in the same plane. (Here i= Angle of incident sound wave and r= Angle of reflection) (Reflection of Sound) (Here 𝞱 i = Angle of incident ray and 𝞱 r  =Angle of reflection) (Reflection of Light) Difference :- (1)👉 The most common difference between light and sound is that we can see light and we can hear sound. (2)👉 Both are energy but sound is a mechanical energy and light is a electromagnetic energy....
