Question

what is the wavelength (in nm) of light having a frequency of 7.8 X 10^13hz

Answer 1

Using the equation:
\[\nu = c \div \lambda\] (With c=3x10^8)
you get a wavelength of 3.85x10-6m or 3850nm

Answer 2

v = lamba f

Answer 3

lambda*

Answer 4

v= 3.0*10^8, ie. the speed of light and f is your frequency so you can just plug it in...:)

Answer 5

is this for physics or chemistry?
