the longest wave length are associated to the littlest frequency, since we have: $\lambda \nu = c = {\text{constant}}$

3. anonymous

ohh okay! so which one has the littlest frequency ?

4. Michele_Laino

5. anonymous

ahh okay!! thank you!! :D

6. Michele_Laino

ultraviolet waves have the highest frequency

7. anonymous

ohh so they are the shortest then?

8. Michele_Laino

yes! the ultraviolet radiation are the shortest, sorry for my previous wrong answer

oh! you were correct!! the question asked for longest! so that means radio waves right? :P

oh i saw your other comment! :P thank you!!
