exacly

you need to expand the formula

you need to use the strict formula not e=mc^2

okay 2 secs ill send you the formula

because we dont use e= for photon

You still believe Einstein?

no its strict formula

yes

?

and its called the strict formula, ive never heard of the variable, it may be different send it to me

You believe in aliens?

Hey I have a question

Is there an admin here?

E = hf

*h*

and *f*

*h* being planks constant and *f* being frequency

because of course photon has no mass *m* would bring back wrong result

but we all know the photon has energy

what

apologies

E

yes must of been a sticky shift key

what

yes well e is elementary charge

so that formula is not aplicable to give any result

you are mistaken

are talking e or E

E is not light

it is measured in J (joule)

yes and do you know what E is ahhaha

yes

okay

ur getting there

so i punch in a formula mc^2 = 1234J

1234J is my *E*

so E is measured in J

i dont say 1234E for my =
