Answer:
" In the Balmer series, the transitions happening in visible range are considered, which range from around 400 nm to 700 nm. The longest wavelength visible in the Balmer series is 656 nm."
Explanation:
Hope this is helpful :)
Is recommend attaching the answer choices; Meters, Liters, Grams are three basic ones
Kinetic energy=1/2mv^2
=1/2(142*10^-3)(42.9)^2=130.6=131J
