This sounds like a stupid question. However my teacher didnt really explain it well.(adsbygoogle = window.adsbygoogle || []).push({});

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 dont 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?
