(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Light waves have very high frequencies compared to sound. The frequency for red light is about 4.6x10^14Hz and for blue 7.0x10^14Hz. What are the periods of these two waves?

2. Relevant equations

T=1/f

3. The attempt at a solution

I used the equation above which is correct in my understanding is this correct?

For Red light i had an answer of 2.173913043x10^-15. I am not sure if this is right so if someone could help me.

If it does seem to be correct how would i write it down as a answer. E.G

The period for red light =2.173913043x10^-15 (S)

I know sounds stupid but just want to be clear.

Thanks in advance
