Sapling week 2,3,4 #19

Question 19 is confusing to me. Could someone help explain it?

I believe the questions may be shuffled, is the question #19 that you're seeing the one that asks: "What would the speed of each particle be if it had the same wavelength as a photon of violet light (wavelength=400.0 nm)?"

If this question is "What would the speed of each particle be if it had the same wavelength as photon of violet light (400nm)?"

You need to use v= h/lambda x m. You need to change the wavelength given from nm to m and change the masses given from g to kg. From there, you just plug the values in and get the answers. Hope this helps!
