Answer:
Like some answer! Make sure to convert in the cute measurement or something
Step-by-step explanation:
Like so i'm not sure if the 4.0x105 is like the x meaning multiplication or what not but I think the x is wayyy more cute than this *, so like ya. But if u ask me you just multiply frequency by wavelength duh? Also this is basic to just use a calculator to convert M to Hz. I converted m to hz because its sooo much prettier of letters like ugh the letter M? bleh.
