Electromagnetic wave
Electromagnetic wave a special gift of nature, You will learn in this post, What is electromagnetic wave ? How electromagnetic wave is created ? Types of electromagnetic wave ? Application and uses of electromagnetic wave, How electromagnetic wave propagate in the space ? History and depth concept of electromagnetic wave, This is very important topic of Physics and really very interesting, I hope and ensure you will enjoy to learn electromagnetic wave, This will be long post but i will suggest you to read complete post, so that you will never forget about electromagnetic wave so lets start.
Electromagnetic wave is special gift of nature
This world work on nature principle, Today you are able to talk 1000 km far distance with other peoples sitting in other countries, Even you can see them. You can go other country in few hours. You can get any information within second.
You can know and get information about planets, stars which are very very far distance from you with the help of science.You know from Physics concept nothing is at absolute rest or in absolute motion in this universe, always taken one body with reference to other object, So rest and motion is always relative, Now you will ask if Earth is moving then why not my home location change ? your home always find at a fixed location this is because you and earth are in same reference frame, in more details i want to say your home location is not changing with respect to surrounding so you feel your home is at rest and is fixed at a point but if you will see from the Sun then you will find your home location is changing due to the Earth rotation.
For more details about relative motion your can refer the previous post Relative motion concept, When reference is change then speed of object is change but this is not valid with light speed it does not depend upon reference frame and light is an electromagnetic wave.
