Shogun:
wait lemme check

Shogun:
hmm its true u do have to use the formula
velocity= frequency*wavelength
so to find wavelenght, change postioins of formulat to (velocity/frequency)
so it would be (3*10^8)/(5*10^14)
u get 6*10^-7

just exactly mana said

but mark scheme only says 6*10
its either they want only 6*10 and if u put any (^number) u still get marks OR u reaaly have to get 6*10 or the mark scheme is worng

but im pretty sure what we did is correct..

ya i guess the mark shceme is incorreect bcuz if u see the metohrd is what we did too soo yaaa
