Question

a sodium street light gives off yellow light that has a wavelength of 589nm find frequency
​

Answer 1

Answer:

We known that v=Cλ=(3×108ms−1)(589×109m)=5.093×10−14s−1

hope it helps u

Answer 2

Answer:

176.7 s^-1

Explanation:

we know that v=c×lambda

=3×10^8×589×10^(-9)

=1767×10^(-1)

=176.7 s^-1
