When in School I learnt 2 things about Light

1. Light is a Wave

I was shown Lenses and other Experiments to proove Light is a wave.

2. When I grew up I was told Light is Electro Magnetic Wave.

Later I was Told
3. Magnetic and Electric Field in a light travel at 90`

Can we Change the angle of movement of Electric & Magnetic Field? How
can we say they are perpendicular.

Later I was told Light has photons and its energy is = h*u

So light is a Particle moving at light Speed.

Then I was told Light is both Particle and Wave

Dont you feel things are getting Complex and Absurd.

After 12 years of my passing out of school I still want to know whats
the correct description of light.


See, there's your problem. Passing out. Maybe if you'd have just
stayed awake, you would know.
