This sounds like a stupid question. However my teacher didnt really explain it well.
Its my first day back at school, cut me some slack thx.
- Calculate the frequency of a lightwave of wavelengh 500nm. Travelling at speed of light (3x10^8 ms-1)
-----------------------------------------
I WILL SUBSITUTE LAMBDA for H (cause i don't know how to type it)
f = ?
h = 500nm
V = 3x10^8 ms-1.
So 500nm x 10^-9 = 0.0000005m
V = fh
Therefore f = h/V
0.0000005m / 3000 000 00ms = ?
Would that be 1.66666666666666666 x10^-15?
BTW- can someone tell me how to input equations?
