it takes a few years to learn

u said E was light

i said no

its not its a measurable thing measured in J

which it is not

it is not

its E=hf

ahaha says the one measuring the mass of a photon

whats the mass of a photon please?

answer me and stop calling me dumb

whats the mass of a photon ?

u want the acount number?

i dont have a credit card, i have a debit card

okay

ask away

malmo

very nice

hows the weather

so whats the mass of light again (photon)

im asking a question

are you not supposed to answer

there we go

and now

72kg

well

thats my weight

it can change based on *g*

but my mass is the same

so back to E=mc^2

if you used E=mc^2 to measure light you would not get an answer

haha

you wouldnt beleive me

no obv not

i wouldnt be sat here

so can i just say E=mc^2 does not give you the energy of light

E=*hf* gives you light

Light is Light, lalaaaalalala

light is photon

its important to understand that becuase the photon has no mass, using E=mc^2 will not work on the photon as the *m* in the equation is mass

so instead we use E=*hf*

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