- Diffraction Pattern on LCD Screen 1 answer
The white bulbs were on my backside on the ceiling as is visible in their reflection in the television. I was sitting almost between (length wise) the bulbs and the television. I took the photographs of their reflection in the LCD.
What are these crosses of rainbow coloured fringes?
Is it interference or diffraction?
And whatever of the 2 it is, how is it happening?
Why only 2 crosses of coloured fringes in the reflection of every bulb , when the angle of each bulb is different?
The bulbs were on my backside so Lloyd's mirror like explanation isn't possible.
Why only 2 crosses of coloured fringes are appearing in the reflection of all the bulbs when they are at different angles?
How is this being caused?
I don't know whether stack exchange is the right place to ask this question by uploading the pictures related to the question , but I couldn't find anyone who could give a reasoning and so I posted it here.
Ever more interesting is that the reflection of the CFL visible in 1st and 2nd pictures is not showing any such pattern.
