its simple bt i m confused...................

pls reply................

listen ,

gamma radiation is an electromagnetic radiation... they do not contain any particles...

to see why,

lets see whats definition of an electromagnetic radiation:

Electromagnetic radiation is a phenomenon that takes the form of self-propagating waves in a vacuum or in matter. It consists of electric and magnetic field components

so at the end we can say gamma rays contain electric and magnetic fields..

and coming to the first part,

let me ask this::

why do u think , the gamma rays should effect the photographic screen because they have high frequencies??

thanks sir................bt dnt em waves can effect photographic screen???

thats what i asked, why do u think waves should effect photographic screen??

may it be wrong or right , say why do u think so..

and regarding your above post , dont call me sir, i am just a student. :P

bcz they hv energy..............they shud b responsible fr photoelectric effect....................

its because:

Like all forms of electromagnetic radiation, gamma rays have no mass or charge and interact less intensively with matter than ionizing particles.

and also gamma radiation loses energy slowly,

okkkk..................thanks a lot..................
