    Energy usually is in Joules, and you'll usually have problems that have answers of just Joules (J). I've seen other answers with units of kiloJoules (kJ = 1000 J), milliJoules(mJ = 0.001 J) and microJoules(μJ 1mJ/1000).

    Waves is a general topic, so I'm just going to be speaking generally about this. Wavelength can be answered with units of meters, but you're going to find nanometers(nm = 1 x 10-9 m) to be a much more common unit on your test. In terms of frequency, you have Hertz(Hz).

    Of course, if I were you, I'd take a quick search on Google just to be sure. After all, I'd feel bad if you failed your test due to prefixes.

    But good luck Fred!
